Eye protection

Be prepared with eye protection, clothing, aprons, and gloves. 

The employer shall ensure that each employee uses appropriate eye or face protection when exposed to eye or face hazards from flying particles, molten metal, liquid chemicals, acids or caustic liquids, chemical gases or vapors, or potentially injurious light radiation. Protective eye and face devices purchased after July 5, 1994 shall comply with ANSI Standard which is incorporated by reference as specified in Sec. 1910.6. 

Indirect-vent, impact and splash resistant goggles are suggested for use with plasticizers. Face shield should additionally be used when working with corrosive, highly irritating, or toxic substances in combination.

Full eye protection should be worn whenever handling acryhc monomers contact lenses must never be worn. Prolonged exposure to Hquid or vapor can result in permanent eye damage or blindness. Excessive exposure to vapors causes nose and throat irritation, headaches, nausea, vomiting, and dizziness or drowsiness (solvent narcosis). Overexposure may cause central nervous system depression. Both proper respiratory protection and good ventilation are necessary wherever the possibiHty of high vapor concentration arises. 

AH operations producing dust require the usual measures to prevent dust in the atmosphere exceeding the allowable daily concentration. If this is not feasible, personal protection devices should be used. Especially when hydroquinone is present as a powder, adequate eye protection should be provided. 

Handling of soluble uranium compounds requires appropriate clothing to prevent skin contact and eye protection to prevent any possible eye contact. Protective clothing requirements for insoluble uranium compounds should prevent repeated or prolonged skin contact. Eye protection for use in handling insoluble uranium compounds should prevent any possibiUty of eye contact. Respirators should always be worn to prevent inhalation of uranium dust, fumes, or gases (38). 

Health and Safety Factors. Isophthahc acid has a low order of toxicity. Inhalation by rats for 4 h at 11.4 g/m showed no toxicity. The LD -level for rats is high at 10.4 g/kg (96). As with terephthahc acid, isophthahc acid was found to form urinary tract calcuh in rats in 90 d when it constituted 3% of their diet. This led to some cancer owing to the presence of the calcuh. Some mild eye irritation is possible, so eye protection should be worn. Otherwise, normal precautions used in handling industrial chemicals should be observed with isophthahc acid. 

Gontact with polyalurninum chloride products may cause bums or irritation to the eyes or skin thus, protective clothing and eye protections are recommended. 

Fatty amine products are normally shipped in 55-gal (208 L), lined and unlined, steel dmms or in tank cars or tank tmcks for bulk shipments. High melting amines can be flaked and shipped in cardboard cartons or paper bags. The amines are corrosive to skin and eyes. Protective splash goggles and gloves should be worn when handling these materials. 

During machining operations, eye protection is recommended during grinding operations, NIOSH-approved respirators for metal fumes and dust are recommended (177). Fine powder of Co is known to cause dermatitis and pulmonary disorders in humans. Most manufacturers supply safety information with their products (178). These should be followed strictly for the welfare of the personnel on the shop floor. 

Polyurethanes. These polymers can be considered safe for human use. However, exposure to dust, generated in finishing operations, should be avoided. Ventilation, dust masks, and eye protection are recommended in foam fabrication operations. Polyurethane or polyisocyanurate dust may present an explosion risk under certain conditions. Airborne concentrations of 25—30 g/m are required before an explosion occurs. Inhalation of thermal decomposition products of polyurethanes should be avoided because carbon monoxide and hydrogen cyanide are among the many products present. 

Many grades of PVB and PVF resias are made, and most are eventually compounded and used as multicomponent products. Individual product MSDSs need to be consulted prior to handling and each product should be handled appropriately and ia accordance with good iadustrial hygiene and safety practices, which iaclude appropriate skin, respiratory, and eye protection. 

Neoprene latexes contain 0.5 to 0.02% residual chloroprene depending on the specific latex type. The amount of free alkaH in the water phase of latexes varies from 0.1 to 0.08% depending on type and age of the material. Eye protection and appropriate skin protection have been recommended for use in situations where splashes or spills are possible. Toxicity and safe handling practices have been recommended for Du Pont types (171). Since compositions may vary with other manufacturers, specific information should be obtained for other products. 

Any commercial sunlamp is satisfactory and should be used with eye protection. Carbon tetrachloride boils gently because of the heat from the lamp.

For the above scales, eye protection should be worn and work should be undertaken in a standard fume-cupboard behind a well-anchored polycarbonate screen. It is advisable to wear a protective apron and hand protection whether leather gauntlets or tongs should be used will be dictated by circumstances. Such measures are recommended but it should be ensured that they do not precipitate a hazard as a result of loss of tactile sensitivity (e.g. dropping a flask, overtightening clamps, exerting excessive pressure when assembling apparatus). The material of gloves needs consideration. (PVC but not rubber is suitable for tert-butyl peroxide.)... 

Transport gases in specially designed trolleys and use eye protection, stout gloves (preferably textile or leather) and protective footwear.
