COSHH worker and contractor information training

COSHH information and training may apply when your work could expose you to a hazardous substance, or when you use a COSHH control or PPE. This can include school workers and contractors, depending on the work they do and the arrangements in place. The key question is not simply your job title: it is whether your work may involve exposure or use of controls or PPE.

This course helps you recognise an information or training need. It does not provide the substance-specific instruction needed for a particular task. If you may be exposed or may use a control or PPE, identify the responsible person or provider and ask what information and task-specific training apply before the work is undertaken.

Hypothetical example: A contractor comes onto a school site to carry out work that may involve a hazardous substance. Although the contractor is not a school employee, the contractor may need information about the school's relevant risks and controls. The school also needs to know whether the contractor is bringing hazardous substances onto the premises. The contractor should therefore be included in the relevant COSHH information exchange.

Workers should understand the outcome of the COSHH assessment and what it means for them. A useful briefing should address the hazards and risks, any workplace exposure limits, and the protective measures needed. Where relevant, it should also communicate the results of exposure monitoring and the collective results of health surveillance. These categories help you check whether the assessment outcome has been explained rather than merely made available.

Before relying on a briefing, look for information that answers five questions: What are the hazards? What are the risks in this work? Are there workplace exposure limits to understand? What protective measures apply? Are relevant monitoring or collective health-surveillance results available to explain? Do not invent a limit or control if the local assessment or responsible provider has not supplied it.

Hypothetical example: A briefing describes a substance's hazard but says nothing about the risks for the planned work or the protective measures. The worked decision is to treat the briefing as incomplete, record those information gaps, and ask the responsible person or provider to explain them. It would be a mistake to fill the gaps using assumptions about a similar substance.

Being told that a control or PPE is required is not the same as being trained to use it correctly. Workers need training in the correct use of controls and PPE. This course does not select PPE, explain how to fit or maintain it, or demonstrate a control method. Those details must come from the relevant school arrangements, COSHH assessment, or responsible provider.

When instruction is unclear, prepare precise questions: Which control applies to this task? What must I be trained to do to use it correctly? Which PPE applies, and what instruction is provided for its correct use? Who provides or confirms the task-specific instruction? Keep the questions open where the local assessment or provider has not supplied the answer.

Hypothetical example: A worker is told, “PPE is needed,” but receives no task-specific instruction. The correct response is not to choose familiar PPE or copy another person's method. The worker should ask the responsible provider or school arrangement what PPE and instruction apply to the task and should not treat the general statement as evidence of correct-use training.

Workers should know what to do after an accident or in an emergency. A spillage is one example of an event that should be covered by the information provided, but this course does not give a spillage procedure or any other site-specific emergency instruction.

Before consulting a local plan or provider instruction, identify what you need to find: how an accident or emergency is recognised, what immediate actions the relevant arrangement requires, who must be informed, and where the applicable local or provider procedure is kept. These details matter because emergency arrangements can depend on the substance, task, and site. Use the current school or provider arrangement rather than relying on this course or memory.

Hypothetical example: A briefing says, “Report any incident,” but gives no clear information about what workers should do after a spillage or whom to contact. The correct decision is to flag an emergency-information gap and seek the applicable local or provider instruction. A likely mistake would be to create a response from general experience; the correction is to follow the defined arrangement once it has been identified and explained.

COSHH information exchange with contractors works in two directions. The school tells contractors about relevant hazardous-substance risks and how those risks are controlled. The school also needs to know whether contractors are bringing hazardous substances onto the premises and how harm to school workers will be prevented. This applies conditionally when the contractor's work may involve hazardous substances or relevant controls.

Before contractor work begins, prepare an information-exchange agenda rather than assuming that one party has all the information. Check: what relevant risks and controls the school must explain; what hazardous substances the contractor will bring; and how the substances and the risks to school workers will be managed. Site-specific arrangements remain conditional on the school's assessment and contractor arrangements.

COSHH information exchange with contractors School: risks and controls: The school provides contractors with information about relevant hazardous-substance risks and how those risks are being controlled. Contractor: understand risks and controls: The contractor receives and considers the school's information about relevant risks and controls. Contractor: substances brought onto premises: The contractor informs the school about hazardous substances the contractor will bring onto the premises. School: manage substances and prevent harm: The school and contractor establish how the substances will be managed to prevent harm to school workers. School: risks and controls leads to Contractor: understand risks and controls. Contractor: substances brought onto premises leads to School: manage substances and prevent harm. Contractor: understand risks and controls leads to School: manage substances and prevent harm.

Hypothetical example: A contractor explains the planned work but does not say whether any hazardous substances will be brought onto the school site. The information exchange is incomplete. The school should ask the contractor to identify any such substances and discuss how harm to school workers will be prevented, while providing the contractor with relevant school risks and controls.

You can prepare for a discussion by grouping each topic as understood, missing, or requiring task-specific instruction. Include the assessment outcome; hazards and risks; workplace exposure limits; relevant monitoring or collective health-surveillance results; protective measures; controls and PPE; accident and emergency information; and contractor substances and arrangements. This structure helps you identify the next discussion point without pretending to deliver the missing technical content.

For each item, write what is known, what is unclear, and who must explain or confirm it. Consult the relevant school COSHH assessment, local arrangement, or training provider where one exists. Look for the reason each item matters: assessment information explains the risks and protective measures; control and PPE instruction supports correct use; emergency information tells workers what to do after an accident or in an emergency; and contractor information exchange helps prevent harm to school workers.

Hypothetical example: A preparation note says that hazards and risks have been explained, but PPE instruction and emergency arrangements are marked “to confirm.” The appropriate next step is to take those two gaps to the responsible person or provider, ask what task-specific instruction and defined emergency information apply, and avoid treating the preparation note as a completed training record or competence sign-off.
