1.2 Analyze the Hazards

Hazards from chemicals are identified, analyzed, and categorized prior to work

being performed. A "hazard" is defined by DOE G 450.4-1A as a source of danger

DOE G 450.4-1A

(i.e., material, energy source, or operation) with the potential to cause illness,

injury, or death to personnel or damage to a facility or the environment (without

regard to the likelihood or credibility of accident scenarios or consequence

29 CFR 1910.1200,

mitigation). OSHA's Hazard Communication Standard (29 CFR 1910.1200)

Hazard

Communication

defines a hazardous chemical as any chemical that poses a physical or health

hazard. EPA defines hazardous wastes in 40 CFR 240-299 [(implementing

regulations for the Resource Conservation and Recovery Act (RCRA)].

Use of an integrated approach to hazard analysis will result in effectively

identifying site and facility hazards, including chemical hazards and the hazards

associated with the disposal of the hazardous chemicals. Analysis can begin at

these levels by assessing chemicals present in quantities greater than the threshold

quantities (TQ) found in 29 CFR 1910.119 and 40 CFR 355. These materials are

29 CFR 1910.119

generally analyzed from the process safety perspective, i.e., potential for a

catastrophic accident with immediate consequences.

Information from these hazard analyses can then be used as the basis for more

detailed analysis at the activity or task level. At this level, hazards associated with a

worker's exposure to chemicals, as a result of their daily activities, are assessed.
