New Isocyanate Range
Control of Substances Hazardous to Health Regulations (COSHH) 2002 requires the employer to measure the concentration of hazardous substances in the air where there is a risk to employees’ health.
Protective equipment should be used to prevent or minimise exposure in the workplace.
Jobs that may involve exposure to isocyanates include painting, foam-blowing and the manufacture of many polyurethane products, such as chemicals, polyurethane foam, insulation materials, furniture, foam mattresses, under-carpet padding, packaging materials, shoes, laminated fabrics, polyurethane rubber and adhesives, and during the thermal degradation of polyurethane products.Isocyanates are a family of highly reactive, low molecular weight chemicals. They are widely used in the manufacture of flexible and rigid foams, fibers, coatings such as paints and varnishes, and elastomers, and are increasingly used in the automobile industry, autobody repair, and building insulation materials
Isocyanate exposure causes irritation of skin, chest tightness, and breathing difficulties including asthma attacks.
The most widely used compounds are diisocyanates, which contain two isocyanate groups, and polyisocyanates, which are usually derived from diisocyanates and may contain several isocyanate groups. The most commonly used diisocyanates include methylene diphenyl diisocyanate (MDI), toluene diisocyanate (TDI), and hexamethylene diisocyanate (HDI). The predominant use of MDI and TDI, is in the manufacture of polyurethanes.
Polyurethanes are produced by reacting diisocyanates with polyols and other chemicals.
a1-cbiss are a UK distributor for supplying a complete range of detectors and monitoring instruments for measuring isocyanates such as MDI, TDI, or HDI
SafeAir Personal Safety Isocyanate Badges
SafeAir is a low cost chemical detector badge allowing companies to perform daily exposure screening. SafeAir badges provide an immediate visual indication when a specific chemical hazard is present.
The SafeAir range consists of direct reading colourimetric badges and colour comparison charts.
The sensor in the SafeAir badge is constructed from a coated indicator layer rather than impregnated paper, thus providing homogeneous and stable colour formation.
The indicator layers are highly sensitive and selective to the targeted hazard. A colour change in the form of an “exclamation mark” warns of the presence of the targeted hazard.
Benefits:
. Easy to use
. Low cost
. Highly sensitive and selective, available for 21 different gases
. Ideal for daily employee screening or leak detection
. Measure TWA exposure
. Minimal training required
. No calibration or laboratory analysis needed
