What substances are included in a COSHH assessment?
A CoSHH assessment typically includes a wide range of substances that could pose health risks to employees. While toxic and dangerous chemicals and hot oils are often the primary focus, it's essential to consider the specific hazards present in your workplace. Additionally, you should consider the hazardous substances that can be produced through processes used while at work - for example, plaster dust being created when sanding a plaster wall, or cutting of plaster board.
What forms do these hazardous substances come in?
These substances can be in diverse forms - including liquids, gases, dusts, toxic / dangerous chemicals, and essentially any material that could potentially harm someone through inhalation, skin contact, ingestion or eye contact.
What effects can these substances cause?
These substances can cause harmful effects in an acute (immediate) or chronic (over time) manner. Immediate effects include irritation, allergic reactions, toxicity, burns, respiratory issues or infection. Chronic effects can include cancer, organ damage, weakened immune system, reproductive issues, respiratory system impact.
The type of exposure such as skin contact, inhalation or ingestion can also influence the type and severity of the effect. The exposure of these substances is also important - hence the Worplace Exposure Limits (WELs) included within the COSHH regulations.
