DUST CONTROL PLAN NOTES / DUST CONTROL PLAN HAZARD ASSESSMENT

PRIOR TO INITIATING WORK, CONTRACTOR AND COR WILL ACCESS THE SCOPE OF THE CONSTRUCTION

ACTIVITIES AND DETERMINE THE POTENTIAL RISK GROUPS INVOLVED BASED ON THE LOCATION OF ACTIVITIES

AND EXTENT AND DURATION OF THE WORK. LOW RISK GROUPS ARE CONSIDERED "OFFICE WORKERS", MEDIUM

RISK GROUPS ARE CONSIDERED ALL INPATIENT AND OUTPATIENT AREAS NOT IN THE HIGH RISK GROUP. HIGH

RISK GROUP DESIGNATION INCLUDES INPATIENT AREAS SUCH AS PEDIATRIC AND ADULT OPERATING/DELIVERY

ROOMS, CATH LABS, MYELO SUPPRESSION UNITS, ICUS, DIALYSIS, NURSERIES AS WELL AS CLINIC AREAS

(CLINICS ASSOCIATED WITH HEMATOLOGY, ONCOLOGY, PEDIATRIC INFECTION DISEASE, OR TRANSPLANT

SERVICES) AND SERVICE AREAS (CENTRAL PROCESSING, STERILE PROCESSING, FOOD PREP & SERVICE AREA

AND PHARMACIES. THE VAMC INFECTION CONTROL GROUP WILL CONFIRM AND APPROVE THE DESIGNATION

PROVIDED IN THIS SUBMITTED DUST CONTROL PLAN. VAMC IS ALSO RESPONSIBLE FOR ANY AND ALL INFECTION

CONTROL MEASURES DETERMINED AND ESTABLISHED BY VAMC POLICY, SUCH AS THE RELOCATION OF HIGH

RISK PATIENTS, APPROVING ALTERNATE TRAFFIC PATHS FOR CONSTRUCTION WORKERS OR ESTABLISH

ALTERNATE TRAFFIC PATTERNS FOR STAFF, PATIENTS AND VISITORS. THE PLAN SHOULD BE REVISED

ACCORDING TO SPECIFIC VAMC POLICIES OR CHANGING CONDITIONS AT THE SITE AS THEY MAY OCCUR.

INTERNAL DEMOLITION AND CONSTRUCTION ACTIVITIES DUST AND DEBRIS CONTROL

• BARRIER SYSTEMS: THE AREA SHOULD BE ISOLATED, AS THE PROJECT REQUIRES. SMALL, SHORT

DURATION PROJECTS GENERATING MINIMAL DUST MAY USE FIRE-RATED PLASTIC SHEETING, BUT

SHOULD BE SEALED AT FULL CEILING HEIGHT WITH AT LEAST 2-FOOT OVERLAPPING FLAPS FOR

ACCESS TO ENTRY. ANY DUST SHALL BE IMMEDIATELY CLEANED IF TRACKED OUTSIDE OF THE

CONSTRUCTION BARRIER. UPON COMPLETION OF THE CONSTRUCTION PROJECT DUST BARRIERS

SHALL BE REMOVED CAREFULLY TO MINIMIZE SPREADING OF DUST AND THE CONTRACTOR SHALL

HAVE TEMPORARY DUST PROTECTION IN PLACE BEFORE REMOVAL OF A PERMANENT BARRIER.

CONTRACTOR PERSONNEL SHALL MONITOR AND PERFORM BARRIER MAINTENANCE AND BE

EDUCATED TO NOTICE SIMPLE CLUES SUCH AS ACCUMULATIONS OF VISIBLE DUST EVIDENCED BY

FOOTPRINTS, OPENED DOORS/WINDOWS EVIDENCED BY PRESENCE OF INSECTS AND FLIES, WET

CEILING TILE, ETC.

• TRAFFIC CONTROL; DESIGNATED ENTRY AND EXIT PROCEDURES SHALL BE DEFINED. EGRESS PATHS

SHOULD BE FREE OF DEBRIS; DESIGNATED ELEVATORS SHOULD BE USED DURING SCHEDULED TIMES;

AND ONLY AUTHORIZED PERSONNEL SHOULD BE ALLOWED TO ENTER THE CONSTRUCTION ZONE.

SIGNAGE SHOULD DIRECT PEDESTRIAN TRAFFIC AWAY FROM THE CONSTRUCTION AREA AND

MATERIALS.

• DEMOLITION DEBRIS: DEBRIS SHOULD BE REMOVED IN CARTS WITH TIGHTLY FITTED COVERS, USING

DESIGNATED TRAFFIC ROUTES. EFFORTS SHOULD BE MADE TO MINIMIZE USE OF ELEVATORS WITH

AN EMPHASIS ON TRANSPORT DURING THE LOWEST PERIOD OF ACTIVITY. DEBRIS SHOULD BE

REMOVED DAILY AND AT TIMES SPECIFIED BY THE VAMC. IF CHUTES ARE USED TO DIRECT DEBRIS

OUTSIDE, HIGH EFFICIENCY PARTICULATE AIR (HEPA) FILTERED NEGATIVE AIR MACHINES SHOULD BE

USED, AND THE CHUTE OPENING SHOULD BE SEALED WHEN NOT IN USE. FILTERS SHOULD BE

BAGGED AND SEALED BEFORE BEING TRANSPORTED OUT OF THE CONSTRUCTION AREA. THE

CONTRACTOR SHALL NOT HAUL DEBRIS THROUGH PATIENT-CARE AREAS WITH PRIOR APPROVAL OF

THE VAMC.

• EXTERIOR WINDOWS: WINDOWS SHOULD BE SEALED TO MINIMIZE INFILTRATION FROM ANY ADJACENT

EXCAVATION DEBRIS.

• CEILINGS THAT ARE REMOVED/MODIFIED TO ALLOW CONSTRUCTION OF ICRA BARRIERS SHOULD BE

REINSTALLED TO PRE-CONSTRUCTION CONDITIONS.

VENTILATION AND ENVIRONMENTAL CONTROLS

• AIR SYSTEM FLOW: DETERMINE WHETHER THE CONSTRUCTION AREA USES FRESH/OUTSIDE OR RE-

CIRCULATED AIR; FILTERS SHOULD BE ADDED OR RETURN VENTS COVERED AS NEEDED WITH FILTER

MATERIAL OR PLASTIC. AIR MUST FLOW FROM CLEAN TO DIRTY AREAS.

• NEGATIVE AIR PRESSURE: THE AIR WITHIN THE CONSTRUCTION AREA MUST BE NEGATIVE WITH

RESPECT TO SURROUNDING AREAS AND WITH NO DISRUPTION OF AIR SYSTEMS OF ADJACENT AREAS.

USE OF THE NEGATIVE AIR PRESSURE SYSTEM WITHIN THE ENCLOSURE TO REMOVE DUST SHOULD

PASS AIR THROUGH AN INDUSTRIAL GRADE, PORTABLE HEPA FILTER CAPABLE OF FILTRATION RATES

OF 300-800 CUBIC FEET PER MINUTE (FT3//MIN), OR EXHAUST AIR DIRECTLY TO THE OUTSIDE IF

APPROVED BY VAMC. IF EXHAUST MUST BE TIED INTO A RE-CIRCULATED AIR SYSTEM, A PRE-FILTER

AND HEPA FILTER SHOULD BE USED BEFORE EXHAUST TO PREVENT CONTAMINATION OF THE DUCTS.

• ADJACENT AREAS: THE STATUS OF SEALED PENETRATIONS AND INTACT CEILING SHOULD BE VERIFIED

DAILY.

• AIR EXCHANGE RATES AND PRESSURE RELATIONSHIPS: VAMC AND/OR CONTRACTOR WILL VERIFY AND

MAINTAIN PROPER RATES IN CRITICAL AREAS NEAR CONSTRUCTION ACTIVITY AND ENSURE AIR IS NOT

BEING RE-CIRCULATED WITHOUT FILTRATION FROM THE CONSTRUCTION AREA ELSEWHERE. VAMC

WILL MAKE DETERMINATION ON PROVIDING FOR THE ACCOUNTABILITY AND FREQUENCY OF TESTING

AIR PRESSURE THROUGHOUT THE PROJECT.

• MANOMETERS SHOULD BE LOCATED ON ICRA PARTITION DOOR AND ON THE NON-CONSTRUCTION SIDE

OF THE PARTITION.
