Acute Health Hazard - The Health Hazard Factor combines the toxicity and the volatility properties of a substance. To assure consistency, Industrial Hygiene will Issue toxicity data as Emergency Exposure Guidelines (EEG) In parts per million. The Health Hazard Factor may. be determined by dividing ^the EEG by the relative ..volatility.. ''Relative? volatll 1ty"equals~vapor*pressure (mm Hg 25* C) divided by 760 rm Hg. For gases, relative volatility Is equal to 1.0. The EEG documentation wl11 be maintained by the H4ES Information Center. Examples for some chemicals are given In Appendix I. If your chemical Is not listed, please call your Industrial Hygienist. Health Hazard scale numbers are based on the following ranges: 5 * 0 - .99 Health Hazard Factor 4 - 1 - 9.9 " 3-10-99 2 100 - 999 Health Hazard Fac. 1 - 1000 - 100,000 0 - >100,000 II. Vapor Quantity - Select the maximum weight of material which would be released as a gas, or would vaporize, during 15 minutes of the "worst case" situation possible. Please be sure to seTect the absolute worst form of pressure, temperature, mechanical failure, run-away reactions, contamination, or human failure that Is possible, but do not arbitrarily assume 100X of the containment would be released and vaporized In 15 minutes.

Process Penalties - The two largest driving forces In generating large amounts of vapor In short periods of time are (1) pressure or overpressure (e.g., liquids well above their boiling points or high pressure gasses) or (2) run-away reactions. Therefore, If either condition exists, a penalty Is applied. If the pressure on the system Is over 10 pslg (1.75 atm. absolute), use_2_for this factor. If the material Is, or can become, thermally unstable below 100C, or Is reactive with common materials like air, water, or other possible contaminants, use 2 for this factor.

Acute Health Hazard - The Health Hazard Factor combines the toxicity and the volatility properties of a substance. To assure consistency, Industrial Hygiene will Issue toxicity data as Emergency Exposure Guidelines (EEG) In parts per million. The Health Hazard Factor may be determined by dividing _the EEG by the relative ..volatility.. /Relative! volat111ty"equals'vapor* pressure (ran Hg 0 25* C) divided by'760 ran Hg. \ For gases, relative volatility Is equal to 1.0. The EEG documentation wl11 be maintained by the HAES Information Center. Examples for some chemicals are given In Appendix I. If your chemical is not listed, please call your Industrial Hygienist. Health Hazard scale numbers are based on the following ranges: 5 0 - .99 Health Hazard Factor ^*4 - 1 - 9.9 3-10-99 2 100 - 999 Health Hazard Fac. 1 1000 - 100,000 0 >100,000 "r II. * ' rl 'J J"' Vapor Quantity - Select the maximum weight of material which would be released asagas, or would vaporize, during 15 minutes of the "worst case" situation possible.
