Irritations to eyes/lungs

Bromine is a volatile liquid at room temperature and pressure and so cannot be measured accurately by pipette. It is also an extremely corrosive compound, irritant to eyes, lungs and mucous membranes. To overcome these difficulties, the bromine required for reaction with the resorcinol is generated in situ by reaction of potassium bromate and potassium bromide in the presence of strong mineral acid.

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. 

Too low to be of military importance highly irritating to eyes, upper respiratory tract, and lungs. CK can cause dryland drowning. 

Symptoms of exposure Very irritating to eyes, nose and respiratory tract. An irritation concentration of 72.00 mg/m in air was reported by Ruth (1986). Exposure to 3,000 ppm for several min may result in serious blistering of skin, lung edema, and asphyxia leading to death (Patnaik, 1992). Ingestion may cause bronchospasm, difficulty in breathing, chest pain, and pulmonary edema. Contact with liquid ammonia or aqueous solutions may cause vesiculation or frostbite (IMIOSH, 1994). 

Fluorine gas is a severe irritant to eyes, skin, and mucous membranes. Acute exposure can cause respiratory tract irritation and pulmonary edema. Chronic exposure can cause mottling of teeth and injury to lungs, liver and kidney. 

Hydrogen telluride is a highly toxic gas and a strong irritant to eyes, nose and upper respiratory tract. Toxic properties are similar to hydrogen selenide. Inhalation can cause damage to lungs, liver and spleen. Short exposure to a high concentration can be lethal. 

Iodine vapors are an irritant to eyes, nose and mucous membranes. Inhalation can cause headache, irritation, and congestion of lungs. Oral intake can produce burning of the mouth, vomiting, diarrhea, and abdominal cramps. Skin contact can cause rashes.

Methylisocyanate is a volatile, reaaive chemical which is highly irritant. Its reactivity means that when humans come into contact with it, it combines with components of body tissues such as the protein in eyes, skin, and lungs. It especially reacts with the sulphur atoms in proteins. These interactions disrupt the lining of the lungs and allow water to enter from surrounding tissues and blood. The result, known as pulmonary oedema, means the victim can drown because their lungs fill up with liquid. Studies in mice exposed to low levels have shown that the chemical is a very potent irritant to the lungs.

Caution Direct liquid contact with skin or eyes may produce severe burns. Vapors are highly irritating to eyes, nose, throat.
