Wash. Admin. Code § 296-843-11005 – Complete a preliminary site evaluation before allowing employees to enter the site

You must complete a preliminary site evaluation by doing all the following:

Collect or develop the following information to the extent available:	•	The site location and approximate size
•	A description of the response activity and the job tasks to be performed
•	The time needed to cover all planned activities
•	The site's topography and all ways to access the site
•	The current status and capabilities of any emergency response team assisting during an emergency
	•	The safety and health hazards expected at the site
	•	The hazardous substances and health hazards at the site, including their chemical and physical properties
	•	All hazardous substance dispersion pathways
	•	An emergency response plan
Have a qualified person evaluate the preliminary site information to identify:	•	Potential site hazards and risks
•	The most appropriate methods to protect employees
•	Conditions that have the potential to cause death or serious harm, including potential inhalation or skin absorption hazards that are immediately dangerous to life or health (IDLH)
	–	Examples include:
			■	Confined space entry
			■	Potentially explosive or flammable environments
			■	Visible vapor clouds
			■	Areas where plants or animals have died
	•	Risks related to specific on-site hazardous substances and health hazards
		–	Examples include:
			■	Exposures exceeding the permissible exposure limits (PELs) or published exposure levels
			■	IDLH concentrations
			■	Potential skin absorption and irritation sources
			■	Potential eye irritation sources
			■	Explosion sensitivity and flammability ranges
			■	Oxygen deficient atmospheres
Have a qualified person prepare an initial site characterization and analysis for the site to:	•	Identify known and suspected health and safety hazards for the site
•	Aid in selecting control methods to protect employees from site hazards
•	Brief employees on site conditions before any work starts
•	Initiate the site-specific health and safety plan (HASP)

Note:

Characterization and analysis of site hazards is an ongoing process for work on the hazardous waste site.
