A.2 NAVSEA LIST OF TARGETED CHEMICALS (N-LTC) APPLICATION EXCEPTION

NOTES.

The following Notes provide rationale for the determination of N-LTC Application Exceptions in accordance with technical publication, NAVSEA Hazardous Material Avoidance Process (T9070-

AL-DPC-020/077-2) dated 28 September 2015. The Notes are referenced in Tables 1 and 2.

A.2.1 Exception: Arsenic and Arsenic Compounds.

A.2.1.1 Batteries.

a. Severity Category: Catastrophic

b. Probability Level: Improbable

c. Rationale: During normal use, arsenic is fully contained in the battery. However, if the battery cell were to be opened or exposed to heat, exposure to arsenic could be harmful to personnel.

d. Risk Assessment Code: Medium

e. Rationale for Exception: Some lead-acid batteries contain enclosed arsenic, which is added to strengthen leaded components. During normal operating conditions, arsenic is contained within the battery, which requires no maintenance and is eventually disposed of as an entire unit upon depletion. This application presents minimal Environmental, Safety, and Occupational Health

(ESOH) risk due to the improbable exposure by inhalation, ingestion, and absorption.

A.2.1.2 Solder.

b. Probability Level: Improbable

c. Rationale: Arsenic in solder poses a minimal risk (Probability Level: Improbable) for activities that only contact solder in place. Activities that perform soldering may have potential occupational exposure to arsenic metallic fume (Probability Level: Remote). These activities are generally well controlled with ventilation.

d. Risk Assessment Code: Medium

e. Rationale for Exception: Arsenic is an impurity of the main constituents of various types of solder. The exposure to solder is low for most NAVSEA activities over its life-cycle because most activities are not engaged in operational maintenance. Activities that perform soldering, such as Naval Shipyards, perform this task using engineering controls (i.e., local exhaust ventilation) and certified personnel. This application presents minimal ESOH risk due to the improbable exposure by inhalation, ingestion, and absorption.

A.2.1.3 Electronic Applications.

b. Probability Level: Improbable

c. Rationale: During normal operation, arsenic is contained within the component and is not disturbed.

d. Risk Assessment Code: Medium

e. Rationale for Exception: During normal operating conditions, electronic components are not abraded or machined and do not generate hazardous dust. This application presents minimal

ESOH risk due to the improbable exposure by inhalation, ingestion, and absorption.

d. Risk Assessment Code: Medium

e. Rationale for Exception: Batteries contain enclosed nickel. During normal operating conditions, nickel is contained within the battery, which requires no maintenance and is eventually disposed of as an entire unit upon depletion. This application presents minimal ESOH risk due to the

A.2.5 Exception: Sulfuric Acid.

A.1.5.1 Sealed Maintenance-Free Batteries.

b. Probability Level: Improbable

c. Rationale: During normal use, sulfuric acid is fully contained in the battery. However, if the battery cell were to be opened or exposed to heat, exposure to sulfuric acid could be harmful to personnel.

d. Risk Assessment Code: Medium

e. Rationale for Exception: Batteries contain enclosed sulfuric acid. During normal operating conditions, sulfuric acid is contained within the battery, which requires no maintenance and is eventually disposed of as an entire unit upon depletion. This application presents minimal ESOH risk due to the improbable exposure by inhalation, ingestion, and absorption.

A.2.6 Exception: Vinyl Chloride.

A.2.6.1 Polyvinyl Chloride.

b. Probability Level: Improbable

c. Rationale: Polyvinyl chloride is fully polymerized and contains no vinyl chloride monomer.

However, vinyl chloride may be released if PVC materials are subjected to intense heat and burned, with potential personnel exposure. Since burning PVC plastic materials are not expected, the risk of exposure is deemed improbable.

d. Risk Assessment Code: Medium

e. Rationale for Exception: Polymerized vinyl chloride is formed through the polymerization of vinyl chloride. This polymerized form presents minimal ESOH risk due to the improbable exposure by inhalation, ingestion, and absorption.

A.2.7 Exception: Cyanide Containing Compounds (includes Nitrile and Cyano Compounds).

A.2.7.1 Nitrile Rubber.

a. Severity Category: Critical

b. Probability Level: Improbable

c. Rationale: Nitrile rubber contains no free cyanide compounds.

d. Risk Assessment Code: Medium

e. Rationale for Exception: Under normal operating conditions, there is minimal potential for the formation of hydrogen cyanide gas from rubber. This application presents minimal ESOH risk due to the improbable exposure by inhalation, ingestion, and absorption.

A.2.8 Exception: Lead and Lead Compounds.

A.2.8.1 Solder.

b. Probability Level: Remote

c. Rationale: Lead in solder poses a minimal risk (Probability Level: Improbable) for activities that only contact solder in place. Activities that perform soldering may have potential occupational exposure to lead metallic fumes (Probability Level: Remote). However, these activities are generally well controlled with ventilation.

d. Risk Assessment Code: Medium

e. Rationale for Exception: The exposure to solder is low for most NAVSEA activities over its life-cycle because most activities are not engaged in operational maintenance. Activities that perform soldering, such as Naval Shipyards, perform this task using engineering controls (i.e., local exhaust ventilation) and certified personnel. This application presents minimal ESOH risk due to the improbable exposure by inhalation, ingestion, and absorption.

A.2.8.2 Sealed Maintenance-Free Batteries.

b. Probability Level: Occasional

c. Rationale: Naval Shipyards cut and move lead ballast on a frequent basis.

d. Risk Assessment Code: Serious (PEO has approval authority)

e. Rationale for Exception: Most NAVSEA activities have no contact with lead ballast. Those activities that install and remove lead ballast, such as Naval Shipyards, do so using strict exposure controls including ventilation and Personal Protective Equipment (PPE). ESOH risks are minimized by the use of proper controls.

A.2.8.4 Industry Standard Metal Alloys with Lead ≤3 Percent.

b. Probability Level: Occasional

c. Rationale: Naval Shipyards perform metal working and hot work with metal alloys.

d. Risk Assessment Code: Serious (PEO has approval authority)

e. Rationale for Exception: Most NAVSEA activities do not regularly machine or abrade metal alloys during the life-cycle of the metal; therefore, lead should not be released to the environment. Some activities, such as Naval Shipyards, routinely machine and perform hot work on metal alloy substrates; however, these operations are performed under strict controls. ESOH risks are minimized by the use of proper controls.

A.2.9 Exception: Lithium and Lithium Compounds.

A.2.9.1 Batteries (per S9310-AQ-SAF-010).

b. Probability Level: Improbable

c. Rationale: During normal use, lithium is fully contained in the battery. However, if the battery cell were to be opened or exposed to heat, exposure to lithium could be harmful to personnel.

d. Risk Assessment Code: Medium

e. Rationale for Exception: Batteries contain enclosed lithium. During normal operating conditions, lithium is contained within the battery, which requires no maintenance and is eventually disposed of as an entire unit upon depletion. This application presents minimal ESOH risk due to the improbable exposure by inhalation, ingestion, and absorption. Batteries require approval through S9310-AQ-SAF-010.

A.2.9.2 Greases.

b. Probability Level: Remote

c. Rationale: During normal use personnel are protected from contact by gloves and other PPE.

d. Risk Assessment Code: Medium

e. Rationale for Exception: Greases contain lithium stearate, which is a soap-like material. There is no free lithium in grease. Lithium greases are considered to have a very low human toxicity by all routes of exposure, and are considered to pose minimal risk to the environment upon release.

A.2.10 Exception: Mercury and Mercury Compounds.

A.2.10.1 Batteries.

b. Probability Level: Improbable

c. Rationale: During normal use, mercury is fully contained in the battery. However, if the battery cell were to be opened or exposed to heat, exposure to mercury could be harmful to personnel.

d. Risk Assessment Code: Medium

e. Rationale for Exception: Zinc air, silver oxide, and alkaline manganese oxide batteries contain small quantities of enclosed mercury. Mercuric oxide batteries may occasionally be required for specific military applications, which contain greater quantities of mercury than the above referenced types. During normal operating conditions, mercury is contained within the battery, which requires no maintenance and is eventually disposed of as an entire unit upon depletion.

This application presents minimal ESOH risk due to the improbable exposure by inhalation, ingestion, and absorption.

A.2.10.2 LCD Displays.

A.2.11.1 Piping.

b. Probability Level: Occasional

c. Rationale: Naval Shipyards and intermediate maintenance facilities (IMFs) machine and perform hot work on nickel alloy piping.

d. Risk Assessment Code: Serious (PEO has approval authority)

e. Rationale for Exception: During normal operating conditions, nickel is not released into the environment or manipulated to generate hazardous dust or fume. Some activities, such as Naval

Shipyards and IMFs perform machining and/or hot work on nickel alloy piping. However, when performed, a variety of exposure controls, including ventilation and PPE, are used.

A.2.11.2 Electrical Connectors.

b. Probability Level: Improbable

c. Rationale: Maintenance procedures do not require any grinding or sanding of the nickel.

d. Risk Assessment Code: Medium

e. Rationale for Exception: Nickel in electrical connectors is present in its elemental state, which presents low toxicity. This form of nickel serves as a sub-layer of the connector coating that personnel will not come in contact with. This application presents minimal ESOH risk due to the

A.2.11.3 Nickel Plating.

b. Probability Level: Occasional

c. Rationale: Nickel is necessary for corrosion protection of certain base metals or as a best practice to cap surfaces to engineering specifications, such as machinery and motor brush plating that are subject to sliding forces. During normal operation, nickel plating is contained within a controlled environment.

d. Risk Assessment Code: Serious (PEO has approval authority)

e. Rationale for Exception: Few activities, such as Naval Shipyards and IMFs, perform plating or subsequent machining of brushplated parts. However, when performed, a variety of exposure controls, including written industrial process instructions, ventilation, and PPE, are used.

Operators are qualified to NAVSEA specification through rigorous training and examination.

A.2.11.4 Industry Standard Metal Alloys.

b. Probability Level: Occasional

c. Rationale: Naval Shipyards and IMFs, machine and perform hot work on nickel alloy metals.

d. Risk Assessment Code: Serious (PEO has approval authority)

e. Rationale for Exception: Most activities do not regularly abrade or machine metal alloys during the life-cycle. Some activities, such as Naval Shipyards and IMFs, perform machining and/or hot work on nickel alloy piping. However, when performed, a variety of exposure controls, including ventilation and PPE, are used.

A.2.12 Exception: Phenol.

A.2.12.1 Phenolic Resins.

b. Probability Level: Improbable

c. Rationale: Phenolic resins do not contain free phenol monomer. This form of polymer is highly stable and heat resistant; it is not likely to release free phenol unless burned.

d. Risk Assessment Code: Medium

e. Rationale for Exception: Polymerized styrene is formed through the polymerization of styrene.

Polystyrene contains no free styrene. This polymerized form presents minimal ESOH risk due to the improbable exposure to styrene by inhalation, ingestion, and absorption.

A.2.14 Exception: Antimony and Antimony Compounds.

A.2.14.1 Batteries.

a. Severity Category: Marginal

b. Probability Level: Improbable

c. Rationale: During normal operating conditions, antimony is contained within the battery.

However, if the battery cell were to be opened or exposed to heat, exposure to antimony could be harmful to personnel.

d. Risk Assessment Code: Medium

e. Rationale for Exception: Batteries contain enclosed antimony, which exists as a residual impurity of other electrode materials. During normal operating conditions, antimony is contained within the battery, which requires no maintenance and is eventually disposed of as an entire unit upon depletion. This application presents minimal ESOH risk due to the improbable exposure by inhalation, ingestion, and absorption.

A.2.14.2 Solder.

b. Probability Level: Remote

c. Rationale: Antimony in solder poses a minimal risk (improbable probability level) for activities that only contact solder in place. Activities that perform soldering may have potential occupation exposure to antimony metallic fume (remote probability level); however, these activities are generally very well controlled with ventilation.

e. Rationale for Exception: The exposure to solder is low for most NAVSEA activities over its life-cycle because most activities are not engaged in operational maintenance. Activities that perform soldering, such as Naval Shipyards, perform this task using exposure controls and certified personnel. This application presents minimal ESOH risk due to the improbable exposure by inhalation, ingestion, and absorption. In addition, antimony-based solders are often used as alternatives to lead-based solders. Lead is far more toxic than antimony.

A.2.15 Exception: Chromium and Non-Hexavalent Chromium Compounds.

A.2.15.1 Chromium Plating.

b. Probability Level: Occasional

c. Rationale: Naval Shipyards and IMFs perform hard chromium electroplating to provide a finish that is resistant to wear, abrasion, heat, and corrosion such as for hydraulic cylinders and rods, engine components, and marine hardware.

d. Risk Assessment Code: Medium

e. Rationale for Exception: The exposure to metallic chromium from plated surfaces is low for most

NAVSEA activities over its life-cycle because most activities are not engaged in operational maintenance. Activities that perform maintenance on metallic chromium plated items, such as

Naval Shipyards, perform this task using exposure controls. In limited cases where hot work is performed on such coated parts, there is an increased risk of producing hexavalent chromium fume. However, where performed, this activity is conducted under strict exposure controls. This application presents minimal ESOH risk due to the improbable exposure by inhalation, A.2.15.2 Industry Standard Metal Alloys.

b. Probability Level: Improbable

c. Rationale: Alloys are not expected to pose a hazard to either shipboard personnel or the environment.

d. Risk Assessment Code: Medium

e. Rationale for Exception: Chromium is generally considered low toxicity when present in an alloy form. Additionally, metal alloys are not regularly abraded or machined during the life-cycle.

A.2.15.3 Trivalent Chromium Coatings and Surface Treatments.

b. Probability Level: Remote

c. Rationale: Installed trivalent chromium coatings present little to no opportunity for exposure.

d. Risk Assessment Code: Medium

e. Rationale for Exception: The exposure to trivalent chromium from coatings is low for most

NAVSEA activities over its life-cycle because most activities are not engaged in operational maintenance. Activities that may occasionally perform maintenance on trivalent chromium coated parts, such as Naval Shipyards, perform this task using exposure controls. In limited cases where hot work is performed on such coated parts, there is an increased risk of producing hexavalent chromium fume. This application presents minimal ESOH risk due to the improbable

A.2.16 Exception: Cobalt and Cobalt Compounds.

A.2.16.1 Industry Standard Metal Alloys.

b. Probability Level: Occasional

c. Rationale: Naval Shipyards and IMFs machine and perform hot work on nickel alloy piping.

d. Risk Assessment Code: Medium

e. Rationale for Exception: Most NAVSEA Activities do not regularly abrade or machine metal alloys during the life-cycle. Activities that perform dust or fume generating activities on metal alloys, such as Naval Shipyards, do so using a variety of exposure controls, including ventilation and PPE.

e. Rationale for Exception: Batteries contain enclosed copper. During normal operating conditions, copper is contained within the battery, which requires no maintenance and is eventually disposed of as an entire unit upon depletion. This application presents minimal ESOH risk due to the

A.2.17.2 Solder.

b. Probability Level: Remote

c. Rationale: Copper in solder poses a minimal risk (improbable probability level) for activities that only contact solder in place. Activities that perform soldering may have potential occupation exposure to copper fume (remote probability level); however, these activities are generally very well controlled with ventilation.

d. Risk Assessment Code: Medium

e. Rationale for Exception: During normal operating conditions, solder installed in components is not contacted. Additionally, for most NAVSEA Activities there is minimal life-cycle exposure to solder because it is installed and discarded without operational maintenance. Activities that perform soldering, such as Naval Shipyards, perform this task using exposure controls and certified personnel. Additionally, few solders contain copper, and those that do rarely exceed 4 percent by weight. This application presents minimal ESOH risk due to the improbable exposure by inhalation, ingestion, and absorption.

A.2.17.3 Piping.

b. Probability Level: Occasional

c. Rationale: Naval Shipyards and IMFs machine and perform hot work on copper piping.

d. Risk Assessment Code: Medium

e. Rationale for Exception: During normal operating conditions, copper is not released into the environment or manipulated to generate hazardous dust or fume. Some activities, such as Naval

Shipyards and IMFs, perform machining and/or hot work on copper piping. However, when performed, a variety of exposure controls, including ventilation and PPE, are used.

A.2.17.4 Electrical and Electronic Components.

b. Probability Level: Improbable

c. Rationale: Hazardous effects would require deliberate ingestion by personnel and prolonged exposure is extremely unlikely.

d. Risk Assessment Code: Medium

e. Rationale for Exception: Copper in electrical and electronic components is present in its elemental form, which presents low toxicity. This form of copper is generally used as a conductive coating in electronics and a base material is electrical components. During normal operating condition, both electrical and electronic applications are not abraded or machined and do not generate hazardous dust. This application presents minimal ESOH risk due to the

A.2.17.5 Plating.

b. Probability Level: Remote

c. Rationale: Most NAVSEA activities only have contact with plated surfaces, which pose no risk.

Those activities that perform plating use exposure controls.

d. Risk Assessment Code: Medium

e. Rationale for Exception: Most NAVSEA Activities do not abrade or machine surfaces of plated items, and therefore do not generate hazardous dust. Activities that may perform copper plating, such as Naval Shipyards, may have occupational exposure to copper generated in the electroplating bath. However, these activities perform plating using a variety of exposure controls, including local exhaust, controlling operating parameters to minimize mist, bath additives, and/or use of brush plating techniques.

A.2.17.6 Antifouling Hull Coatings.

b. Probability Level: Remote

c. Rationale: Most NAVSEA activities only have contact with painted surfaces, which pose no risk.

Those activities that apply coatings use appropriate exposure controls.

d. Risk Assessment Code: Medium

e. Rationale for Exception: Copper-based antifouling coatings are used on >98% of the Fleet. The few ships that are coated with other than Copper-based paints are either experimental demonstration platforms or are Aluminum hulled and Copper-based paints represent galvanic corrosion risk. Paints are applied in an industrial dry-dock setting where standards for worker and environmental safety apply.

A.2.17.7 Industry Standard Metal Alloys.

b. Probability Level: Occasional

c. Rationale: Naval Shipyards routinely perform operations that produce dusts and fumes of copper.

d. Risk Assessment Code: Medium

e. Rationale for Exception: Most NAVSEA activities do not regularly machine or abrade metal alloys during the life-cycle of the metal. Some activities, such as Naval Shipyards, routinely machine and perform hot work on metal alloy substrates; however, these operations are performed using exposure controls. ESOH risks are minimized by the use of proper controls.

A.2.18 Exception: Selenium and Selenium Compounds.

A.2.18.1 Electronic Components.

b. Probability Level: Improbable

c. Rationale: During normal operating conditions, selenium is contained within the component and is not disturbed.

d. Risk Assessment Code: Medium

e. Rationale for Exception: During normal operating conditions, these components are sealed and are disposed of intact. This application presents minimal ESOH risk due to the improbable

A.2.19 Exception: Silver and Silver Compounds.

A.2.19.1 Electrical and Electronic Applications.

b. Probability Level: Improbable

c. Rationale: During normal operating conditions, silver is contained within the component and is not disturbed.

d. Risk Assessment Code: Medium

e. Rationale for Exception: Elemental silver is generally used as a conductive coating in electronics and a base material is electrical components. During normal operating conditions, both electrical and electronic applications are not abraded or machined and do not generate hazardous dust.

A.2.19.2 Plating.

b. Probability Level: Remote

c. Rationale: Most NAVSEA activities only have contact with plated surfaces, which poses no risk.

Those activities that perform plating use exposure controls.

d. Risk Assessment Code: Medium

e. Rationale for Exception: Most NAVSEA Activities do not abrade or machine surfaces of plated items, and therefore do not generate hazardous dust. Activities that may perform silver plating, such as Naval Shipyards, may have occupational exposure to silver generated in the electroplating bath. However, these activities perform plating using a variety of exposure controls including local exhaust, controlling operating parameters to minimize mist, bath additives, and/or use of brush plating techniques. This application presents minimal ESOH risk due to the improbable exposure by inhalation, ingestion, and absorption.

A.2.19.3 Solder.

b. Probability Level: Remote

c. Rationale: Silver in solder poses a minimal risk (improbable probability level) for activities that only contact solder in place. Activities that perform soldering may have potential occupation exposure to silver fume (remote probability level); however, these activities are generally very well controlled with ventilation.

e. Rationale for Exception: The exposure to solder is low for most NAVSEA activities over its life-cycle because most activities are not engaged in operational maintenance. Activities that perform soldering, such as Naval Shipyards, perform this task using exposure controls and certified personnel. This application presents minimal ESOH risk due to the improbable exposure by inhalation, ingestion, and absorption.
