Products supplied by Martins Rubber Co Ltd are produced from 5 main Polymer groups; a) Acrylonitrile-Butadiene co-Polymer (nitrile). b) Ethylene-Propylene. c) Polychloroprene (Neoprene*). d) Fluoroelastomer. (Viton*) e) Silicone Rubber Compounds are complex chemical mixtures, which may contain hazardous ingredients. However, products supplied by the company are in the form of fully vulcanised mouldings which, as far as Martins Rubber Co Ltd is aware, present no known health hazard if the following information is adhered to.
No specific safety requirements are necessary. Possible mild irritant for personnel with sensitive skin, barrier cream is recommended. Wash hands before eating. Normal hygiene standards apply. To avoid the possibility of irritating gaseous emissions, products should be stored in polythene bags and resealed after use. Do not ingest.
Seals, mouldings and compounds are designed to be used within specific parameters, e.g. Pressure, media and operating temperature ranges. When used correctly, products present no known health hazards. However certain compounds (see special notes II & I) can present a hazard if used at higher than recommended operating temperatures, or if involved with fire.
For disposal of unused products, landfill is preferred conforming to local and national regulations. Burning is not recommended, except in an approved incineration process. * Viton and Neoprene is the registered trademarks of the Du Pont Company.
Most rubber compounds will support combustion, giving rise to dense and toxic fumes; in the event of fire all personnel to immediately leave the area. The use of dry powder and foam is recommended, firefighters to use breathing apparatus reference to COSHH Regulations Schedule 1 and HSE document EH40-90 must be made.
Highly toxic products of combustion, including Hydrogen Fluoride, Carbonyl Fluoride, Carbon Monoxide and low molecular weight Fluorocarbon fragments, can be generated in a fire involving fluoroelastomer compounds. Hydrogen chloride is produced by a Neoprene Fire. Personnel fighting such a fire must wear face masks and self-contained breathing apparatus. All unprotected personnel must leave the area immediately. Anyone exposed to fumes must seek appropriate medical attention.
Fluoroelastomers involved in a fire or subjected to temperatures above 275°c must only be handled by personnel wearing Neoprene or PVC gloves. Skin contact must be avoided to prevent exposure to highly corrosive residues such as Hydrogen Fluoride. Such residues should be decontaminated by washing in a Calcium Hydroxide solution.
