Flammable materials ventilation data

Most sealants use mineral-based fillers, which may contain small amounts of crystalline silica. Crystalline silica is a known cause of silicosis, a debilitating disease of the lung. Some but not all sealants use flammable ingredients, but for those that do, proper inserdng and grounding are needed to prevent potential explosions. In general, sealants should be used in areas that have good ventilation, A careful review of the material safety data sheet is fundamental before use of any sealant. 

Hydrogen sulfide is a highly toxic and flammable gas (explosion limits 4.3 % - 46 %). Being heavier than air, it tends to accumulate at the bottom of poorly ventilated spaces. Although very pungent at first, it quickly deadens the sense of smell, so potential victims may be unaware of its presence until it is too late. For safe handling procedures, a hydrogen sulfide material safety data sheet (MSDS) should be consulted. 

Safety glasses must be worn in the laboratory at all times. Material safety and data sheets should be read prior to the start of the experiment. All chemicals should be considered hazardous from a standpoint of flammability and toxicity. Appropriate safety gloves must be worn when using organic solvents so that no skin contact is permitted. Care must be taken to use organic solvents either in a well-ventilated area or in a hood. Avoid breathing the fumes or sources of electrical sparks. The GPC instrument, including solvent reservoir and waste container, should be vented to a fume hood or other exhaust system. 

Flammable Liquid, Poison SAFETY PROFILE Suspected carcinogen with experimental carcinogenic data. Poison by ingestion and inhalation. Mutation data reported. An eye, skin, and mucous membrane irritant. A lachrymating material that can cause corneal burns and is very dangerous to the eyes. Caution Keep away from heat and open flame. Keep container closed. Use with adequate ventilation. Extremely irritating to eyes, skin, mucous membranes. When necessary, the lachrymatory effect of the vapors may be counteracted by ammonia fumes.
