The hazardous constituent of diesel fuel is benzene. Benzene comprises approximately 0.002 to 0.011 % of the total fuel mixture. Dermal contact with diesel fuel can cause minor eye irritation and dermal rash. Prolonged breathing of vapors can impact on the central nervous system. Diesel fuel is not generally expected to have acute systemic toxicity by ingestion. Ingestion of diesel fuel and/or subsequent vomiting can result in aspiration of light hydrocarbon liquid which can cause pneumonitis. There is no Federal or State OSHA PEL or ACGIH TLV standard established for diesel fuel. 3.3 HEAT STRESS Adverse climatic conditions (both heat and cold) are important considerations in planning and conducting site operations. Ambient temperature effects can include physical discomfort, reduced efficiency, personal injury and increased accident probability. Heat stress is of particular concern due to the prevailing climactic conditions in California. All appropriate procedures regarding heat stress shall be met. Additionally, one or more of the following control measures can be used to help control heat stress: 1. Provisions of adequate liquids to replace lost body fluids. Employees must replace water and salt lost from sweating. Employees must be encouraged to drink more than the amount required to satisfy thirst. Thirst satisfaction is not an accurate indicator of adequate salt and fluid replacement. (It is important to note, however, that ingestion of liquids will not be permitted in the contaminated zone. Workers should go to the break area to obtain the necessary liquids.) 2. Establishment of a work regimen that will provide adequate rest periods for cooling down based upon individual site conditions encountered on any given day. This may require additional shifts or workers. 3. Cooling devices such as cooling vests can be worn beneath protective garments. 4. All breaks are to be taken in a cool, shaded area (77 degrees Fahrenheit is ideal).
