How does the NB Occupational Health and Safety Act apply to residential painting contractors working on ladder-access exteriors in Fredericton?

In New Brunswick, the Occupational Health and Safety Act (OHSA) and its General Regulation (O.C. 91-191) apply to residential painting contractors the moment they employ workers — meaning any painter with employees working on ladder or scaffold-access exteriors in Fredericton must comply with NB's working-at-heights requirements, regardless of whether the project is residential or commercial.

This is an area where many smaller NB painting operations underestimate their legal exposure. A sole proprietor working alone occupies a grey zone, but the moment a second worker is on site — even a helper or apprentice — the full weight of the OHSA applies. WorkSafeNB enforces these requirements and can issue stop-work orders and significant fines for non-compliance on residential job sites.

Working at Heights: What the Regulation Requires

Under NB's General Regulation, fall protection is required when workers are exposed to a fall of 3 metres (approximately 10 feet) or more. For exterior residential painting in Fredericton, this threshold is crossed almost immediately on a two-storey home — a standard two-storey clapboard house puts a painter at 4.5 to 6 metres at the eaves. The regulation requires employers to use guardrails, travel restraint systems, fall arrest systems, or safety nets when working at these heights. Extension ladders alone do not satisfy fall protection requirements for sustained work at height — they are a means of access, not a fall protection system.

Scaffolding used on NB residential exteriors must meet the requirements set out in the General Regulation, including proper base support, platform width (minimum 500mm/20 inches for light-duty), guardrails on open sides above 3 metres, and regular inspection. Pump jacks and bracket scaffolding — common on Fredericton's older two-storey homes — must also comply with these standards.

Employer Responsibilities Under the OHSA

A residential painting contractor operating as an employer in NB must maintain a written health and safety program if they have 20 or more employees, but core duties apply to all employers regardless of size. These include identifying and eliminating hazards, providing workers with adequate training and supervision, supplying appropriate personal protective equipment, and ensuring the work site is safe. For exterior painting specifically, this means conducting a site-specific hazard assessment before work begins — accounting for ground conditions, overhead obstructions, proximity to power lines (a serious concern on older Fredericton residential streets with overhead service drops), and weather conditions.

Power line proximity deserves particular attention. WorkSafeNB regulations require a minimum clearance distance from energized overhead lines — metal ladders and wet scaffolding near a home's electrical service entrance are a genuine hazard that painters must assess and manage before setting up any equipment.

WorkSafeNB Coverage

Separate from the OHSA itself, residential painting contractors with employees must carry WorkSafeNB workers' compensation coverage. As a homeowner hiring a painting contractor in Fredericton, you should always ask for a WorkSafeNB clearance letter before work begins — if a worker is injured on your property and the contractor lacks coverage, you may face liability exposure. WorkSafeNB clearance letters can be verified directly through the WorkSafeNB website.

A Note on Scope

Because this touches on legal compliance and occupational health regulations, I want to be straightforward: for specific legal interpretation of the OHSA or WorkSafeNB requirements for your situation, consult directly with WorkSafeNB or a qualified occupational health and safety professional. WorkSafeNB offers free consultation services and their prevention officers can conduct site assessments. Their website (worksafenb.ca) has the full text of the General Regulation and working-at-heights guidelines.

If you're a homeowner looking to hire an exterior painting contractor in Fredericton, verifying WorkSafeNB coverage and asking how they manage fall protection on two-storey work is a completely reasonable question to put to any contractor before signing. Browse painting contractors through the New Brunswick Construction Network directory at newbrunswickconstructionnetwork.com/directory?trade=painting — and don't hesitate to ask the right safety questions before work begins.
