Risk Rating Calculation
Likelihood Severity
3 Probable: Likely to occur each year; Has occurred recently 3 Death/hospitalisation
2 Possible: Likely to occur in 10 years; History of it happening 2 > 3 day injury
1 Remote: Not likely to occur in 10 years; Has not occurred 1 < 3 day injury
Risk Rating (RR) = Likelihood of Realisation of Hazard (L) × Severity of Hazard Being Realised (S)
Low = 1–2 Leave until last Medium = 3–4 Leave until later (set firm completion date) High = 6–9 ACT NOW

Method statement (plans of work)
A method statement is often used for a high-risk situation. Its aim is to prevent KEY TERM
accidents or dangerous situations from occurring. A suitable and sufficient Method statement: the
method statement should be a practical and useful document that clearly record of how management
describes a safe working method for a work team to follow easily. Senior wants the job to be done.

A method statement must be clear and precise, otherwise it will be considered
unsuitable or insufficient for the task. Typical information to be included in
a method statement includes drawings, plans, specifications, schedules, risk
assessments, site inspection reports, manufacturers’ information, current
regulations and official guidance associated with protecting work areas.
The purpose of the method statement is to compile into one document the
control measures and findings for a range of risk assessments associated with
a specific job. The information is then handed to employees so that they have
clear and detailed guidance on how to safely carry out the task.
