Heat stress prevention

Is there a written heat stress prevention program as part of the SAHP or safety and health SOPs ... 

CSDP occupational and environmental health program, the committee believes that the program described in the referenced documents has been fully implemented and that medical records are being maintained as prescribed. The committee noted that medical surveillance for chemical agents and heat-stress prevention programs are carried out rigorously. The committee concluded that the program is comprehensive, professional, and adequate to meet the known occupational health needs of CSDP workers.

For example, for a eaustie spill response performed by employees on site, the log indieated that one worker experieneed heat exhaustion during the eleanup and was absent from work the next day, likely due to heat exhaustion from the eaustie spill. No other entries in the log dis-eussed the use of heat stress monitoring or prevention praetiees, suggesting that sueh praetiees were not always implemented on the site.

In view of the favorable effects of trehalose on protein stability and prevention of aggregation, why is this solute rapidly removed from the cells after heat stress Although the precise mechanisms involved are not clear, it is apparent that trehalose interferes with the subsequent refolding of heat-denatured proteins. Perhaps... 

Unfortunately, PPE used for protection from pesticides can increase the potential for heat stress. The PPE features that keep pesticides out also serve to prevent body heat from escaping. People cannot work as long or as hard when the PPE they are wearing reduces the body s ability to maintain its thermal balance. Under some enviromnental conditions, certain activities cannot be performed withont jeopardizing the health of the worker unless auxiliary cooling is provided. The risk that PPE may aggravate heat stress must be balanced with the PPE s potential worker protection benefits. 

Heat stress is a constant and potentially severe health threat to the worker in toxicological protective clothing. The combination of exposure to solar radiant energy or enclosed areas with high temperatures, metabolic heat production, and the use of impermeable clothing (which prevents evaporative cooling) place the chemical worker at high risk for heat injury. 

Numerous textbooks and other sources discuss thermoregulation and physiological responses to heat healthcare providers may benefit from a review of these subjects. This chapter will address the evaluation of heat stress and preventive measures. 

Alagirusamy, 2010). Clothing is considered as a system that interacts with the body and must support thermoregulation of the body by maintaining its thermal balance (constant body core temperature of 37 °C) and providing a comfortable microclimate next to the skin (Li and Wong, 2006). Prevention of heat stress could lead to improved competitive performance for the athlete, whereas unnecessary heat and moisture next to the skin could have adverse effects on both performance and health. 

Sweating is the body s principal method for removing excess heat. Sweat consists of water and electrolytes (salts). An individual at rest and not under stress, sweats about one liter per day. The sweating rate for an individual under stress of heavy woric or high temperatures is about four liters in four hours. The body must replace water and electrolytes to prevent heat stress or sickness. This is why many people who try to walk out of stranded situations in a desert with only a few liters of water fail and die. They do not realize how profusely they will sweat and how dehydrated they will become. In the pages that follow, we will take a closer look at temperature hazards the process technician may be exposed to in the processing industry.
