Whilst laboratories, hospitals, schools and factories are likely to store hazardous chemicals, they need to be stored correctly and not under a sink or at the back of a cupboard.
There are a few potential risks with hazardous chemicals:
- If they mix with each other (e.g. through leakage).
- If they are involved in a fire or have flammable properties.
The management of substances means you must only keep the minimum amount and lowest hazardous substances possible. Another consideration is if the chemical is toxic, harmful or corrosive etc. Staff who use these must be trained in its safe use etc. Keep these chemicals in a safe and secure place and ensure that they are only accessed by competent staff.
Most general cleaning work can be carried out without either chemicals or with low hazardous products. Choose substances that do not have a warning sign on the back as these can be left under the sink or in wash rooms without concern. Remember to avoid storing chemicals in damp conditions as the packaging can be affected. If you do store chemicals in large quantities, then remember plastic trays to stand the chemicals on are a good idea in case of spillages/leakages. This will reduce the risk of accidental mixing and help with the ease of clearing up if necessary.
Work in confined spaces such as drains, pits, tanks and other enclosed places can kill if workers are overcome by low oxygen levels or a build up of hazardous gases. There can be little warning before unconsciousness takes hold leaving very little time to get help.
It can be fumes in the atmosphere which can cause the harm along with other hazards which need to be considered including flammable substances, explosive atmospheres, heat stress, free-flowing solids and liquids. These are known as “specified risks” within the Confined Space Regulations 1997.
The HSE’s guidance was updated in December 2014. It is worth reading if you oversee confined spaces or work within them and forms the HSE’s primary source of information on the subject. The wording has been made clearer than in the previous version, although the meaning has unchanged.
“A confined space is not necessarily
A) Enclosed on all sides,
B) Small and/or difficult to work in,
C) Difficult to get in or out of or
D) A place where people do not regularly work.”
A confined space could include a spray booth, wood pellet store, an unventilated room where fumes are generated, tank containing flammable residues, manholes and sewers.
