2023年2月8日 · What are the possible health effects and risks from exposure to immunotoxic chemicals? Back to top. The type of adverse health effects that workers may have after exposure to immunotoxic chemicals will depend on how the immunotoxic substance affects the immune system, the dose (how much), and the time exposed (how long).
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, appropriate foam, water spray or fog. Specific Hazards Arising from the Chemical: Heat from fire can cause a rapid build-up of. pressure inside cylinders. Explosive rupture and a sudden release of large amounts of gas may result. Cylinder may rocket.
