Keep reading to find out what to do if a corrosive chemical spills in your workplace.

The dangers of a corrosive chemical spill

Corrosive chemicals are very hazardous. They damage and destroy other substances they come into contact with, from living tissue to metal and stone. These substances can harm people in several different ways:

  • Ingesting a corrosive chemical can burn your mouth, throat, oesophagus, and stomach.
  • Inhaling corrosive vapours can irritate the tissues in your throat, nose, lungs, eyes, and windpipe. It may also cause coughing and breathing problems.
  • Long-term exposure to and absorption of corrosive chemicals can damage your internal organs and weaken your bone structure. It might affect your nervous system, too.
  • Contact with corrosives, such as it splashing on the skin, instantly damages tissue. It will irritate, blister, and burn the skin, and any injuries to the eyes could lead to permanent scarring and even blindness.

They can even ignite combustible chemicals which can lead to fires, resulting in structural damage to buildings, and making workplaces unsafe and unusable for long periods of time.

To prepare for potential spills, you must be aware about the hazards associated with each chemical you store and use at your site. This is an essential part of a chemical spill risk assessment which you are legally obligated to carry out.

You should also write response procedures for each of the hazards, and ensure your workers have the equipment and training required to follow them.

How to clean up a corrosive chemical spill

Alert your staff that a spill has occurred

As soon as you become aware that a spill has happened, notify supervisory personnel and staff about the hazard. If the chemical is dangerous, you may need to evacuate your workers to protect your health. You might also need to alert surrounding businesses and the authorities.

Should the chemical have injured someone, seek medical attention by contacting the emergency services.

Stop the spill getting worse

If safe to do so, make sure the chemical is no longer spilling by closing valves, covering openings with putty, or putting containers upright.

Only a trained professional wearing full personal protective equipment (PPE) and respiratory protective equipment (RPE) should do this. This will ensure they don’t get any corrosive chemical on their skin, breathe in harmful vapours, and reduce their risk of absorption.

Turn off any heat or ignition sources that could create a fire if the chemical is flammable. Any substances that could react with the spilled chemical must be secured.

Ventilate the affected area – or entire facility, when required – by opening windows. You may need to supply workers with gas masks with their own air supply.

Contain the spilled chemical

The chemical will then need to be contained to stop it spreading. Trained professionals will use absorbent materials, like boons and spill socks, and block access to the affected area to stop people going near it.

Spill kits for hazardous chemicals can help you control the spill and clean up the chemical, but they should only be used by people trained to use them, like specialist cleaners.

Clean up the chemical and dispose of the waste

Professional cleaners will collect the material used to contain the spill and dispose of it according to local regulations. A hazardous chemical spill may require plastic pails and drums. They will also need to dispose of equipment they used to clean up the spill, like brooms.

Then, they should thoroughly clean the spill area to ensure all traces of the corrosive chemical has been removed. You can find out more about what to do when a dangerous chemical spills on the Health and Safety Executive’s website.

Why only professionals should carry out hazardous spill clean up

Firstly, specialist cleaners trained in dealing with hazardous chemicals will have the expertise, equipment, and PPE to clean up the entire spill safely and thoroughly.

Should you attempt it yourself, you may be putting your health at risk and might not clean up all traces of the chemical which could put people in danger.

Cleaners will also be able to quickly clean it up. A rapid hazardous chemical spill procedure is essential to minimising damage to your workplace and keeping your workers safe.
