Maleic Anhydride. The ACGIH threshold limit value in air for maleic anhydride is 0.25 ppm and the OSHA permissible exposure level (PEL) is also 0.25 ppm (181). Maleic anhydride is a corrosive irritant to eyes, skin, and mucous membranes. Pulmonary edema (collection of fluid in the lungs) can result from airborne exposure. Skin contact should be avoided by the use of mbber gloves. Dust respirators should be used when maleic anhydride dust is present. Maleic anhydride is combustible when exposed to heat or flame and can react vigorously on contact with oxidizers. The material reacts exothermically with water or steam. Violent decompositions of maleic anhydride can be catalyzed at high temperature by strong bases (sodium hydroxide, potassium hydroxide, calcium hydroxide, alkaU metals, and amines). Precaution should be taken during the manufacture and use of maleic anhydride to minimize the presence of basic materials. 

Pseudocumene is shipped ia barges, tank cars, tank tmcks, isocontainers, and dmms. Mesitylene is shipped ia tank tmcks, isocontainers, and dmms, whereas durene is shipped molten ia heated tank tmcks, isocontainers, and occasionally as a cast soHd in dmms. Mesitylene, pseudocumene, and hemimellitene are classified as flammable Hquids the higher homologues are classified as combustible. The higher melting PMBs requite additional precautions when handled in the molten state to avoid thermal bums. Detailed shipping and handling procedures are described in manufacturers material... 

Finely powdered pyrites, especially in presence of moisture, will rapidly heat spontaneously and ignite, particularly in contact with combustible materials [1]. Inert gas blanketing will prevent this [2], Precautions to reduce the self-ignition hazards of powdered pyrites, and the explosion hazards of pyrites-air mixtures in the furnaces of sulfuric acid plants have been detailed and discussed [3], Further studies on minimum moisture content of Portuguese pyrites for safe transportation and storage are reported [4],... 

Thermal burns result from the radiant heat emitted by a hydrogen fire and absorbed by a person, which is directly proportional to many factors including exposure time, burning rate, heat of combustion, size of the burning surface, and atmospheric conditions (mainly wind and humidity). For instance, thermal radiation flux exposure level of 0.95 W/cm2 may cause skin burns in 30 s. Cryogenic burns may result from contact with cold fluids or cold vessel surfaces. Exposure to large liquefied hydrogen spills could result in hypothermia, if proper precautions are not taken [17]. 

Precautions and storage On exposure to heating, ethylene glycol dinitrate may cause violent combustion or explosion in work areas and release toxic fumes and nitrogen oxides. Also, it may explosively decompose on shock, friction, or concussion. Storage of ethylene glycol dinitrate requires areas... 

Mutation data reported. Spontaneously combustible take special storage and handling precautions. When heated to decomposition it emits toxic fiimes of Li. 

Step 16. The combustion products leave the furnace at 250 C and flow through the chlorine vapor heat exchanger (this stream is the flue gas referred to in Step 3) and then to a flare, where any carbon monoxide and residual hydrocarbons in the gas are burned and the products released to the atmosphere. The flare is a safety precaution if the furnace operates as intended, the CO and hydrocarbon content of the flue gas should be negligible.
