What are the five steps to risk assessment?

The Health and Safety Executive (HSE) advises employers to follow five steps when carrying out a workplace risk assessment:  

Step 1: Identify hazards (anything that may cause harm)  

Employers have a duty to assess the health and safety risks faced by their workers. Your employer must systematically check for possible physical, mental, chemical and biological hazards.  

A common classification of hazards is as follows:  

• physical: such as lifting, awkward postures, slips and trips, noise, dust, machinery, computer equipment, and so on; 
• mental: including excess workload, long hours, working with high-need clients and bullying. These are also called 'psychosocial' hazards, affecting mental health and occurring within working relationships. 
• chemical and other substances, such as asbestos, cleaning fluids, aerosols and so on. 
• biological: including risk of tuberculosis, hepatitis and other infectious diseases faced by healthcare workers, home care staff and other healthcare professionals.  

Step 2: Decide who may be harmed, and how  

Employers should identify who is at risk within their organisation among their full- and part-time staff, and also risks faced by agency and contract staff, visitors, clients and other members of the public on their premises.  

Employers must review work routines in all the different locations and situations where their staff are employed. For example:  

• home care supervisors must take due account of their client's personal safety in the home as well as ensuring safe working and lifting arrangements for their own home care staff; 
• in a supermarket, hazards are found in the repetitive tasks at the checkout, in lifting loads, and in slips and trips from spillages and obstacles in the shop and storerooms. Staff face the risk of violence from customers and intruders, especially in the evenings; 
• in call centres, workstation equipment (such as desk, screen, keyboard and chair) must be adjusted to suit each employee.  

Employers have special duties towards the health and safety of young workers, disabled employees, nightworkers, shiftworkers, and those who are pregnant or breastfeeding.  

Step 3: Assess the risks and take action  

This means employers must consider how likely it is that each hazard could cause harm and what action to take, if any, to reduce the level of risk. Even after all precautions have been taken, some risk usually remains. The employer must do everything ‘reasonably practicable’ to protect people from harm and decide for each remaining hazard whether the risk remains high, medium or low.  

Step 4: Make a record of the findings  

Employers with five or more staff are required to record in writing the main findings of the risk assessment. This record should include details of any hazards noted in the risk assessment, and action taken to reduce or eliminate risk.  

This record provides proof that the assessment was carried out and is used as the basis for a later review of working practices. The risk assessment is a working document that should be available to you to read. It should not be locked away in a cupboard.  

Step 5: Review the risk assessment  

A risk assessment must be kept under review to:  

• ensure that agreed safe working practices continue to be applied (for example, that management's safety instructions are respected by supervisors and line managers); and 
• take account of any new working practices, new machinery or more demanding work targets.
