Working at height risk assessment

The hierarchy is the point

The Work at Height Regulations 2005 require work at height to be avoided where it is reasonably practicable, and otherwise done from a place that prevents a fall, or that reduces the distance and the consequences. Collective protection, such as a scaffold with edge protection, comes before personal protection.

The four library hazards below are not interchangeable. A roof edge, a ladder used along the eaves, a scaffold that has no guard rail yet, and a decorator painting a whole elevation from a ladder are different decisions. Score them for the site in front of you.

Fall from the roof edge, through a fragile rooflight, or from a ladder

From the roofer library, task: Pitched roof tile replacement. Who might be harmed: Operatives and people below

Before controls: 20 High. After controls: 10 Medium. These scores are a prompt. Score the job yourself.

• Follow the hierarchy in the Work at Height Regulations 2005: avoid the work at height if a repair from a safe platform is reasonably practicable, otherwise prevent a fall, otherwise mitigate it.
• Provide edge protection or a properly designed scaffold. A roof ladder is secured over the ridge and used with edge protection or another justified system.
• Cover or barrier fragile rooflights. Do not step on them.
• Stop in high wind, ice, or heavy rain. Wet moss is not a walking surface.

Fall from a ladder used as a place of work along the eaves

From the roofer library, task: Gutter and downpipe replacement. Who might be harmed: Operatives

Before controls: 16 High. After controls: 4 Low. These scores are a prompt. Score the job yourself.

• Use a scaffold or podium so both hands are free and the operative is prevented from falling.
• If a ladder is used only to reach the platform, it is footed or tied and extends far enough above the step-off.

Fall of a scaffolder during erection, before guard rails exist

From the scaffolder library, task: Independent scaffold erection. Who might be harmed: Scaffolders

Before controls: 20 High. After controls: 10 Medium. These scores are a prompt. Score the job yourself.

• Use a recognised erection method that protects the erector, such as an advanced guard rail system where the equipment provides it.
• Follow the Work at Height Regulations 2005 hierarchy. A harness is a last resort and only with anchors and rescue.
• Stop in high winds or ice.

Fall from a ladder used to paint a whole elevation

From the painter and decorator library, task: Exterior painting. Who might be harmed: Operatives

Before controls: 16 High. After controls: 4 Low. These scores are a prompt. Score the job yourself.

• Paint elevations from a scaffold or podium, not from a ladder leaned along the wall.
• Stop if the platform is incomplete or the weather makes the surface slippery.
