APPENDIX D Stress evaluation – heat Heat stress may occur year round in areas with heat producing equipment such as in foundries, kitchen, or laundries. In Minnesota, high temperatures and humidity’s are common during the summer with daily temperatures routinely varying to 30 degrees. This variation does not always allow people to become acclimatized and stay acclimatized, thereby increasing the risk of heat stress.
reproduction health hazard – any agent that has a harmful effect on the adult male or female reproductive system of the developing fetus or child. SDS – safety data sheet sensitization – an immune-response reaction state in which further exposure elicits an immune or allergic response. silicosis – a condition of massive fibrosis of the causing shortness of breath. skin – notation used to indicate possible exposure to a chemical by absorption through the skin. specific gravity – STEL – short term exposure limit. subcutaneous – beneath the skin. target organ effects – chemically caused effects upon specifically listed organs an systems. teratogen – an agent or substance that caused physical defects in developing embryo. TLV (threshold value) – a term established by ACGIH to express the airborne concentration of a material to which nearly all workers can be exposed day after day without adverse effects. TWA (time-weighted average) – the expression for average exposure which accounts for fluctuating levels during a given time period. UEL (upper explosive limit) – the highest concentration of a material in air that will produce an explosion. unstable – tending toward decomposition or other unwanted chemical change during normal handling or storage. vapor density – the weight of a vapor or gas compared to the equal volume of air. pressure – vertigo – a feeling of revolving in space; dizziness, giddiness. viscosity – measurement of the flow properties of a material. water reactive – a chemical that releases a hazardous gas, often violently, upon contact with water.
