GENERAL SITE SAFETY AND �HEALTWPLAN . . - HAZARD ASSESSMENT CHART Hazard Action Hazard Elimination or Risk Reduction Procedure and Proper Protective Equipment Level ventilation will be used to reduce flammable vapor concentrations to below 10 % of the lower explosive limit. • If air monitoring indicates hydrocarbon vapor concentrations are present in the work area at concentrations greater than 10 % of the lower explosive limit, measures will be taken immediately to reduce ambient hydrocarbon vapor concentrations . Heat > 75 F Monitoring for heat stress will be performed when ambient air temperatures are above 75° Fahrenheit ( F) and anytime when employees are wearing chemically resistant clothing . Effects of heat-related stress/illnesses are progressive and are characterized as follows : ■ Heat Rash — Caused by exposure to heat, humid air, and irritation by wet, scratching clothing . Heat rash interferes with the kidneys' ability to tolerate heat. ■ Heat Cramps — Caused by excessive perspiration in which fluids and electrolytes are not adequately replaced . Symptoms are muscle cramps and stomach pain , which occur after work has stopped . ■ Heat Exhaustion — Caused by stress on various organs due to the body trying to cool itself. Symptoms include pale , moist skin , profuse sweating , weakness , and dizziness . Cool victim and seek medical assistance immediately. ■ Heat Stroke — The most serious consequence of heat stress . It is caused by total failure of the body' s cooling system . Symptoms are red , dry , hot skin ; lack of perspiration , nausea ; rapid pulse , and unconsciousness . The body must be cooled immediately to prevent death . Seek medical attention immediately . C) Plenty of fluids and water will be provided for drinking and cooling . Employees will be encouraged to drink during all breaks . When temperatures are above 85° F , breaks will be taken more often . CHEMICAL Gasoline Any amount Gasoline is a flammable organic compound . of free Nitrile gloves will be used when handling gasoline gasoline :ZIf clasoline vapors are present respiratory rotection may be required see below Gasoline 50 ppm Approved respiratory protection will be required when concentration levels exceed the action level . Vapors Only approved respirators with organic vapor cartridges will be used . Respirators will be used in accordance will be the WPI Respiratory Protection Program Carbon 5000 ppm Carbon Monoxide is a colorless , odorless gas than can cause poisoning and death in high concentrations . Carbon monoxide monoxide is generated while truck and diesel generators are operating . Do not allow carbon monoxide gas to accumulate in confined spaces . Truck and diesel exhaust will be directed away from places frequented by people, Diesel Fuel Any free Diesel fuel is a combustible organic liquid ,
