• ! <br /> Heat stress monitoring should be performed by a person with a <br /> current first aid certification who is trained to recognize heat <br /> stress symptoms . For monitoring the bodys recuperative abilities <br /> to excess heat, the following techniques will be used. Other <br /> methods for determining heat stress monitoring, such as the wet <br /> bulb globe temperature (WBGT) Index from American Conference of <br /> Governmental Industrial Hygienist (ACGIH) TLV Booklet can be used. <br /> To monitor the worker, measure: <br /> 0 Heart rate. Count the radial pulse during a 30 second period <br /> as early as possible in the rest period. <br /> Early symptoms of heat stress include clammy skin, confusion, <br /> dizziness, fainting, fatigue, rashes, cramps, and nausea, which may <br /> lead to impaired functional ability, putting a worker and his co- <br /> workers at risk. Continued heat stress may lead to heat stroke and <br /> possible death. Avoiding over protection, careful training and <br /> frequent monitoring of personnel who wear protective clothing, <br /> judicious scheduling of work and rest periods, and frequent <br /> replacement of fluids can protect against the threat of suffering <br /> heat stress. If symptoms of heat stress are noted, the affected <br /> personnel will be properly treated at the site. If symptoms <br /> persist, they will be brought to the nearest medical facility for <br /> observation and treatment. <br /> 2.2.3 Heavy Equipment <br /> Heavy equipment shall be operated in a safe manner, according to <br /> Cal-OSHA guidlines .
