This COSHH assessment template is written for UK site-based work: builders, roofers, joiners, decorators, cleaning teams, maintenance contractors and anyone using paints, solvents, adhesives, cement or cleaning chemicals. Use it before work begins with a hazardous substance, and keep it with the rest of the paperwork for that job.
Below you will find the template structure, a fully completed cement dust example, a step-by-step process and the mistakes that most often come up on site. If you would rather not maintain files, Graftly provides the same assessment as a guided digital workflow you can complete from your phone.
What is a COSHH assessment?
COSHH stands for the Control of Substances Hazardous to Health. A COSHH assessment is a written record of the hazardous substances involved in a piece of work, how people could be exposed to them, and what is being done to keep that exposure as low as reasonably practicable.
The purpose is straightforward: protect the people doing the work and anyone nearby from harm that often builds up slowly — dermatitis, asthma, silicosis — rather than showing up as an accident on the day. It also gives you a clear record when a client, principal contractor or inspector asks how a substance is being controlled.
A COSHH assessment is narrower than a general risk assessment, which covers all hazards for a task. In practice the two sit together: the risk assessment covers the job, the COSHH assessment covers the substances used within it.
When is a COSHH assessment required?
You need one whenever work involves a substance that could harm health — including dust and fumes created by the work itself, not just products that arrive in a container. Common examples on UK sites:
Paints
Solvent vapours, skin and eye irritation
Solvents and thinners
Flammable, vapour inhalation
Adhesives
Isocyanates, vapours, skin sensitisation
Cement and mortar
Corrosive when wet, silica in dust
Silica dust
Cutting, grinding, chasing, drilling
Fuels and oils
Flammable, skin contact, fumes
Cleaning chemicals
Acids, alkalis, bleach mixing risks
Sealants and mastics
Vapours and skin sensitisation
Resins and hardeners
Sensitisation, burns, fumes
Aerosols
Propellants, confined-space build-up
Assessments should be completed before work begins, not written up afterwards. If a new product arrives on site mid-job, assess it before it is opened.

Example completed COSHH assessment: cement dust
Cement is one of the most common COSHH assessments on UK sites, and a useful worked example because it involves both skin contact and respirable dust. Adapt the detail to your own product, quantities and site conditions.
- Product name
- General purpose Portland cement (25kg bags)
- Manufacturer
- Example UK cement supplier — SDS dated March 2026
- Hazardous substance
- Portland cement containing respirable crystalline silica; alkaline (corrosive) when mixed with water
- Intended use
- Mixing mortar and screed for blockwork and floor levelling, approx. 8 bags per day, 3 days per week
- Exposure routes
- Inhalation of cement and silica dust during pouring and mixing; skin and eye contact with wet cement; accidental ingestion via unwashed hands
- Persons affected
- Bricklayers, labourers, apprentices, nearby trades, site visitors and occupants of adjacent areas
- Health effects
- Cement burns and dermatitis from wet cement, eye damage, respiratory irritation, and long-term risk of silicosis from repeated dust exposure
- PPE
- Nitrile or waterproof gloves, long sleeves, safety boots, goggles when pouring, FFP3 disposable mask where dust cannot be controlled at source
- Control measures
- Cut bags low and pour slowly to limit dust, mix outdoors or in a ventilated area, use pre-mixed products where practical, on-tool extraction or water suppression when cutting cured mortar, no dry sweeping — use a Class M vacuum
- Storage
- Keep bags dry, off the ground on pallets, under cover and away from water ingress; do not stack above chest height
- Emergency actions
- Skin: wash immediately with clean water and remove contaminated clothing. Eyes: irrigate for 15 minutes and seek medical attention. Inhalation: move to fresh air. Spill: contain dry powder, avoid raising dust, vacuum rather than sweep
- Disposal
- Set waste cement in a designated container and dispose of via licensed construction waste collection; do not wash residues into drains
- Review date
- Reviewed 12 months from issue, or immediately if the product, quantity, method or site conditions change

How to complete a COSHH assessment
- 1
Identify the substance
List every product used on the job, including the ones people forget — cleaning chemicals, aerosols, fuels and dusts created by the work itself.
- 2
Read the Safety Data Sheet
Get the current SDS from the manufacturer or supplier and check the date. Sections 2, 4, 7, 8 and 13 cover hazards, first aid, storage, controls and disposal.
- 3
Identify the hazards
Note what the substance can actually do — irritation, burns, sensitisation, respiratory damage, fire risk — and how serious it could be.
- 4
Assess exposure
Think about how the substance is used on this site: quantity, frequency, ventilation, confined spaces, and who is nearby as well as who is using it.
- 5
Decide the controls
Work down the hierarchy: substitute for a safer product, control at source with extraction or suppression, then use PPE and RPE to cover what is left.
- 6
Record the findings
Write the assessment down, brief the team on it, and keep it with the other paperwork for that job so it can be found when someone asks.
- 7
Review regularly
Set a review date, and review sooner if the product, method, quantity or site conditions change, or after a near miss.
Step six is where most records fall down. Briefing the team is easier if the assessment is paired with a toolbox talk on the same substance, and anything that goes wrong should feed into your near miss and incident records so the next review has something to work from.
Common COSHH mistakes
Using old Safety Data Sheets
Formulations and classifications change. An SDS several years old may no longer describe the product in the van.
Listing PPE but not specifying it
"Gloves and mask" is not a control. Record the glove type and the RPE rating, and check face fit where it matters.
No review date
Without a review date, nobody knows whether the assessment still reflects the work being done.
Poor storage controls
Storage is part of the assessment. Flammables, corrosives and open containers in a hot van are a common gap.
No employee briefing
An assessment nobody has read changes nothing on site. Brief it, ideally alongside the toolbox talk for that task.
Generic copy and paste
Copying another firm's assessment carries their controls, their quantities and their site — not yours.
Why digital COSHH assessments save time
Most firms do not have a COSHH problem so much as a filing problem. The assessment gets written once, saved to a laptop, emailed to one person and then cannot be found when the site manager asks for it six weeks later. Working digitally changes the workflow rather than the obligation.
COSHH records are most useful when they sit next to the rest of the job paperwork. Graftly keeps them alongside RAMS, risk assessments, method statements and site logs, so one job has one set of documents rather than several folders in different places.
How COSHH fits with your other site documents
A COSHH assessment rarely stands alone. The risk assessment covers the task, the method statement explains how the work is carried out, and together they usually form the RAMS pack a client asks for. The COSHH assessment sits inside that pack, covering the substances the method statement relies on.
Frequently asked questions
What is a COSHH assessment?
A COSHH assessment records the hazardous substances used on a job, how people could be exposed, and the control measures and PPE needed to keep exposure as low as reasonably practicable.
Is a COSHH assessment a legal requirement?
Under the Control of Substances Hazardous to Health Regulations, employers must assess the health risks from hazardous substances before work starts and put suitable controls in place. Employers with five or more employees are normally expected to record the significant findings.
Who completes a COSHH assessment?
Someone competent and familiar with the work — often a supervisor, site manager, contracts manager or the business owner in a smaller firm. They need access to the Safety Data Sheet and an understanding of how the substance is actually used on site.
How often should COSHH assessments be reviewed?
Review whenever the substance, product, quantity, method of use or site conditions change, after an incident or near miss, and otherwise on a regular cycle — many firms use an annual review date.
Can I use one template for every chemical?
You can reuse the same template structure, but each substance needs its own assessment. Hazards, exposure routes, PPE, storage and emergency actions differ between products.
Do COSHH assessments expire?
There is no fixed expiry date, but an assessment stops being valid once it no longer reflects the substance, the work or the controls in use. That is why a recorded review date matters.
Can I complete COSHH assessments digitally?
Yes. Digital COSHH assessments can be completed on a phone or tablet on site, stored centrally, searched later and exported as PDFs for clients or principal contractors.
What is the difference between COSHH and a risk assessment?
A general risk assessment covers all hazards for a task. A COSHH assessment focuses specifically on substances hazardous to health, such as dusts, fumes, chemicals and vapours.
Do I need a COSHH assessment for cement?
Yes. Wet cement is corrosive and cement dust contains respirable crystalline silica, so cement work normally needs a COSHH assessment covering dust control, skin protection and washing facilities.
Where should COSHH records be kept?
Keep COSHH records where the team can actually reach them — ideally alongside the RAMS and risk assessments for the same job, rather than in a folder back at the office.
