As a versatile and easy-to-use product, WD-40 has become an essential part of many British workshops. From lubricating locks to removing rust, it has a range of uses that make it an ideal choice for tackling tricky jobs.
While WD-40 is widely used across workplaces throughout the UK, understanding safe and correct usage is essential. This is the UK's ultimate guide to WD-40 COSHH risk assessment and usage.
Key Takeaways
- WD-40 requires a proper COSHH risk assessment before use in the workplace
- Key hazards include inhalation of vapours and skin irritation
- Appropriate protective equipment must be worn depending on the task
- Regular review and updating of assessments is essential for compliance
Why Risk Assessment is Critical
Conducting risk assessments before using any product is critical for workplace safety. When using WD-40, attention must focus on potential dangers if misused.
Key Hazards of WD-40
The primary hazards associated with WD-40 that must be considered in your assessment include:
- Inhalation of fumes or vapours - Can cause sore throats, headaches and dizziness in some individuals
- Contact with skin - May cause irritation with prolonged or repeated exposure
- Flammability - WD-40 has a flammability rating of 3, making fire safety a critical consideration
First Aid Preparation
It is essential to maintain first aid kits on-site and ensure workers understand product hazards before use. Being prepared for potential exposure incidents can prevent minor issues from becoming serious health concerns.
Safe Usage of WD-40
Proper protective equipment is essential when working with WD-40. Appropriate protective clothing such as safety glasses, gloves and overalls may need to be worn depending on what task is being completed.
Safety Recommendations
To ensure safe usage of WD-40 in your workplace, follow these essential guidelines:
- Wear eye protection when spraying to prevent contact with eyes
- Ensure operational ventilation systems are functioning properly in enclosed spaces
- Work outdoors when possible to maximise natural ventilation
- Never mix different lubricant types as this can cause unpredictable chemical reactions
- Avoid hazardous chemical reactions by keeping WD-40 away from incompatible substances
- Keep away from open flames or ignition sources at all times due to flammability
Ventilation is Key
Working in well-ventilated areas or outdoors significantly reduces the risk of vapour inhalation. When this is not possible, ensure mechanical ventilation is in place and functioning correctly.
Consequences of Poor COSHH Assessment
A poorly conducted COSHH assessment can have serious consequences for your workplace. Here are the major failures that can result from inadequate assessment:
1. Ignoring Potential Hazards
Dangerous materials may not be correctly identified, meaning these hazardous substances can remain present and put staff in danger. Without proper hazard identification, workers may be unknowingly exposed to risks that could have been prevented.
2. Improperly Assessing Substances
Incomplete assessments result in inadequate employee protection. When the full scope of a substance's hazards is not understood, the control measures put in place may be insufficient to protect workers from harm.
3. Missing Important Regulations
Oversight of legislation or industry guidelines can leave your organisation exposed to legal action and regulatory penalties. COSHH regulations are updated periodically, and failure to keep current can result in non-compliance.
4. Inaccurate Exposure Estimations
Risks can easily be misjudged or underestimated due to improper evaluations. If exposure levels are not accurately assessed, workers may be exposed to harmful concentrations of substances without adequate protection.
5. Outdated Assessments
Failing to update assessments with changing regulations leaves your workplace vulnerable. Assessments should be reviewed regularly and whenever there are changes to processes, products, or regulations.
Legal Obligation
Employers are legally obligated to comply with Control of Substances Hazardous to Health (COSHH) regulations when using substances like WD-40 in their workplace. Failure to comply can result in significant fines, legal action, and harm to employees.
