With respect to following delivery orders, one could expect being involved with the following potentially hazardous environments/materials:

Delivery Order Option 1 – Fixture Installation

· Lifting of heavy equipment

· The need for overhead crane (lifting of heavy equipment)

· Use of power tools for assembly and installation into foundation (which may be loud and could produce projectiles) Delivery Order Option 2 – Engineering Services

· There are no anticipated hazardous conditions or materials with respect to engineering services Delivery Order option 3 – Starboard Main Float Manufacture (Overhaul)

· Moving of heavy equipment (fixtures) and parts

· Use of overhead crane

· Extensive riveting (loud and repetitious)

· Sheet metal fabrication

· Use of power tools for assembly

· Hazardous Materials

· Hydraulic Fluid

· RTV Sealant

· Silicone

· Primer and Paint

· Chemical conversions (passivation, alodine, anodization)

· Hydraulic Actuations (up 3000 PSI)

· Moving objects - pinch points and hydrofoil arc

· Foil arc consists of large and heavy metal objects actuating about the main float causing an area where objects could cause injury

· Electrical testing consisting of 28 Volts

· Using pressurized air (could produce projectiles)

· Machining and welding
