COSHH and Dangerous Goods in the Warehouse: What Every Worker Must Know
Many warehouses store substances that can be harmful if handled incorrectly — from cleaning chemicals to industrial solvents, aerosols, paints, and batteries. The law requires employers and workers to understand the risks and follow proper procedures.
What Is COSHH?
COSHH stands for Control of Substances Hazardous to Health. It is a set of regulations that require employers to:
- Identify hazardous substances in the workplace
- Assess the risks they pose to workers
- Implement control measures to reduce those risks
- Provide information, instruction, and training
- Monitor exposure and carry out health surveillance where needed
Common Hazardous Substances in Warehouses
- Cleaning chemicals — industrial cleaners, bleach, degreasers used in warehouse maintenance
- Aerosols — pressurised containers that are flammable and can explode if damaged
- Batteries — lithium batteries in particular pose fire risks if damaged or short-circuited
- Paints and solvents — flammable and producing harmful vapours
- Adhesives — industrial glues used in packing can cause skin and respiratory irritation
- Diesel and oils — from forklift maintenance and vehicle operations
Your Responsibilities as a Worker
Under COSHH regulations, you must:
- Follow all safe working procedures provided by your employer
- Use PPE when required — gloves, goggles, masks, aprons
- Read safety data sheets (SDS) and COSHH assessments for substances you work with
- Report any spills, leaks, or damaged containers immediately
- Never eat, drink, or smoke in areas where hazardous substances are stored
- Report any symptoms of exposure — skin irritation, breathing difficulties, dizziness
Storage Requirements
Dangerous goods must be stored according to specific rules:
- Flammable substances in fire-rated cabinets or designated areas
- Chemicals separated by type — some substances react dangerously if mixed
- Clear labelling with GHS hazard symbols on all containers
- Spill kits available in storage areas
- Temperature-controlled storage for substances that are sensitive to heat
- Adequate ventilation in storage areas to prevent vapour buildup
What to Do in an Emergency
- Spill — do not attempt to clean up unless you have been trained and have the correct equipment. Alert your supervisor and evacuate the area if fumes are present
- Skin contact — wash the affected area with plenty of water for at least 20 minutes. Remove contaminated clothing
- Eye contact — flush with clean water for at least 15 minutes using an eye wash station
- Inhalation — move to fresh air immediately and seek medical attention if symptoms persist
- Fire — raise the alarm and evacuate. Do not attempt to fight chemical fires unless trained
COSHH awareness is a legal requirement and a practical necessity. TRS Recruit ensures all temporary workers receive appropriate safety briefings before starting assignments involving hazardous substances. If you have not received adequate training at a site, tell us immediately.
