	Title	Specification(s)	Objective(s)
	2.0103.2a Worker safety	Follow all worker safety specifications in SWS 2.0100 Global Worker Safety section	Prevent injury Minimize exposure to health and safety hazards
	2.0103.2b Mercury	When replacing existing thermostats, identify and dispose of any mercury containing thermostats in accordance with Environmental Protection Agency ( EPA EPA U.S. Environmental Protection Agency, www.epa.gov ) guidance	Protect worker and occupant from mercury exposure
	2.0103.2c Asbestos	Suspected asbestos hazards will be identified in furnaces (e.g., gaskets), wood stoves, zonal heating devices, electrical wiring insulation, boilers, and pipe insulation and corrected in accordance with EPA EPA U.S. Environmental Protection Agency, www.epa.gov guidance Workers will take precautionary measures to avoid exposure	Protect worker and occupant from asbestos exposure
	2.0103.2d Personal protective equipment ( PPE PPE Personal protective equipment )	Workers will wear personal protective equipment ( PPE PPE Personal protective equipment ) as needed to protect themselves against exposure to hazards (e.g., pests, sewage, flooded duct work, mold, chemicals, scat, viruses) Long sleeves and long pants should be worn as additional protection from liquid nitrogen and other hazardous materials	Protect worker from exposure to hazards Protect worker from skin contact with liquid nitrogen
	2.0103.2e Combustible gas detection	Worker will check for presence of combustible gas leaks before work begins Leaks will be repaired before work is performed	Protect worker and occupant from exposure to hazards
