Basic information on the characteristics of flammable and toxic properties of raw materials, semi-finished products, finished products and production waste

Characterization of production hazards

Table No. 7.1 shows the characteristics of the flammable and toxic properties of raw materials, semi-finished products, finished products and production waste.

Table No. 7.1 Explosive and fire hazardous, toxic properties of raw materials, semi-finished products, finished products and production waste.

Name of raw materials, semi-finished products, finished products (substances, % mass), production wastes Hazard class (GOST12.1.007-76) Aggregate state at norms. conditions Vapor (gas) density in air Specific gravity for solid and liquid substances g / cm 3 Solubility in water, % wt. Is it possible to ignite or explode if exposed to it, (yes, no) Temperature, °С Flammable limits MPC in the air of the working area prod. premises Characteristics of toxicity (impact on the human body) Literature
boiling melting self-ignition ignition outbreaks the start of the exotherm. decomposition concentration (% vol.) temperature, ° С air suspension (g / cm 3 ) dispersion
water oxygen
lower top. lower top. lower
Broad fraction of light hydrocarbons. gas / liquid No yes, in the presence of an ignition source 1.3 9.5 900/300 Low toxicity. May cause death through prolonged inhalation and absorption (penetration) through the skin. Causes frostbite of the skin (outwardly it looks like a burn). With minor poisoning, headache, dizziness, drowsiness, nausea, vomiting, irritation of the eyes and throat are observed. Pain in the heart, mental disorders, loss of consciousness, respiratory arrest. Has a narcotic effect on the human body TU 38.101524-93, GN 2.2.5.1313-03, No. 2055.

Fraction hydrocarbon liquid minus 104 1.0 15.5 Vapors of the hydrocarbon fraction act on the central nervous system, cause headache, dizziness, have a narcotic effect, nausea, irritate the respiratory tract, eyes, if swallowed, burns the oral cavity, esophagus, stomach, pain in the abdomen. TU 0272-078-00151638-2007
Coolant (diesel fuel). liquid 0.875 0.001 No yes, in the presence of an ignition source 1.4 8.0 600/300 Has a narcotic effect. At high concentrations of vapors causes chronic poisoning, headache, weakness. Getting on the skin degreases the skin. GOST 305-82, GN 2.2.5.1313-03, No. 1076.
Turbine oils T-22, MS-20 liquid 0.9 No yes, in the presence of an ignition source -15/ -18 186/ 148/ 182/ (spray can) Low toxicity, prolonged exposure causes dermatitis. GOST 32-74. GOST 21743-76. GN 2.2.51313-03 No. 1192.

End of table No. 7.1
