Night working introduces additional hazards including reduced visibility, fatigue, isolation, and impaired communication.
The Working Time Regulations 1998 limit night workers to an average of eight hours in any 24-hour period.
Artificial lighting must provide sufficient illumination for the specific task, access routes, and emergency escape paths.
Fatigue is a major factor in night shift incidents — reaction times slow and decision-making deteriorates after midnight.
Noise restrictions may apply during night hours, limiting the types of activities that can be carried out.
Communication is harder at night — radios, site phones, and clear briefing procedures become even more critical.
Plant and vehicle visibility is reduced at night despite headlights — additional lighting and banksmen are essential.
Lone working risk increases at night due to fewer personnel on site and delayed emergency response.
Night workers must have access to the same standard of welfare facilities as daytime workers, including heated rest areas.
A specific night working risk assessment must address lighting, fatigue, security, communication, and emergency procedures.

Fatigue kills	Tiredness impairs judgement and reaction times — night shift workers are significantly more likely to be involved in accidents.
Reduced visibility	Darkness hides hazards that are obvious during the day — adequate artificial lighting is essential for every work area and route.
Legal limits	The Working Time Regulations 1998 limit night work hours — excessive shifts without proper rest increase incident risk dramatically.

Don't

Complete a night working risk assessment before any night shift operations begin.
Ensure adequate artificial lighting covers all work areas, access routes, and escape paths.
Take scheduled rest breaks and manage fatigue with proper sleep before night shifts.
Use radios or phones to maintain communication with supervisors and other night workers.
Wear hi-vis clothing with reflective strips for maximum visibility in artificial light.
Ensure a banksman is present for all plant movements during night operations.
Check that welfare facilities are open, heated, and stocked for night shift workers.
Follow noise restrictions and only carry out permitted activities during night hours.
Report any security concerns, trespassers, or suspicious activity to site management.
Brief all night workers on emergency procedures and the location of first aid provision.

DON'T work at night without adequate artificial lighting in your work area.
DON'T ignore fatigue — report tiredness and take breaks before making mistakes.
DON'T exceed the working time limits for night shifts without proper management approval.
DON'T work in isolation at night without a communication device and check-in procedure.
DON'T rely on vehicle headlights alone — site lighting must illuminate the full area.
DON'T allow plant to reverse at night without a banksman using illuminated signals.
DON'T accept poor welfare provision at night — you have the same rights as day workers.
DON'T carry out noisy activities during restricted hours without specific authorisation.
DON'T leave the site unsecured — lock gates and compounds during night shift breaks.
DON'T skip the night shift briefing — hazards and emergency procedures must be understood.
