Duties of employers

Rachel Okoye, the vice-president of operations, asked Elena for a plain-language list of what the law expects of Harrowgate Foods Ltd. as an employer. 'Not the whole binder,' she said. 'One page I can put in front of the leadership team, so every manager and supervisor knows what we are promising.' Elena's page became the basis for this lesson. It is organized around a simple question that regulators and courts keep asking after something goes wrong: what did the employer do, before the incident, to make the work safe?

The general duty

At the top of every employer's list is the general duty. Nova Scotia's Act requires every employer to take every precaution that is reasonable in the circumstances to ensure the health and safety of persons at or near the workplace. The phrase 'every precaution that is reasonable' sets the standard. It does not require an employer to guarantee that nobody will ever be hurt, but it does require the employer to identify foreseeable hazards and to take the steps a reasonable employer in that industry would take to control them. Courts measure 'reasonable' against what was known, what was practicable and what others in the industry were doing.

The general duty then breaks down into more specific duties. They overlap, and a good safety program addresses all of them together.

1. Identify and assess hazards

An employer cannot control a hazard it has not found. Nova Scotia's regulations require hazard assessment in many specific situations, and the general duty implies it everywhere. In practice that means walking the workplace, looking at each task, talking to the people who do it, reviewing incident and near-miss reports, reading safety data sheets and manufacturer manuals, and repeating the exercise when equipment, processes or people change. The assessment should be written down, because an assessment that exists only in someone's head cannot be checked, shared or proven.

At Harrowgate Foods Ltd., the hazard assessment for night sanitation had been done three years earlier by the day-shift safety coordinator, using the written procedure rather than observing the actual work. It listed lockout as the control for the spiral conveyor but did not notice that the disconnect was on a far mezzanine, or that the cleaning window had been cut from four hours to two and a half. A hazard assessment that describes work as imagined, rather than work as done, gives a false sense of security.

2. Control hazards using the hierarchy of controls

Once hazards are found, the employer must control them. The accepted order of preference is the hierarchy of controls: eliminate the hazard if possible; substitute something less hazardous; use engineering controls such as guards, interlocks and ventilation; use administrative controls such as procedures, training, signs and scheduling; and, as the last line of defence, provide personal protective equipment. Regulators and courts expect employers to work down this list and to explain why a higher-level control was not practicable before relying on procedures and PPE.

For the spiral conveyor, Harrowgate Foods Ltd.'s response after the injury followed the hierarchy. Engineering: a lockable disconnect was installed at floor level beside the spiral, and an interlocked access gate was added so that opening it stopped the drive. Administrative: the sanitation schedule was extended back to four hours, the lockout procedure was rewritten with the crew and posted at the machine, and supervisors were required to verify lockout on every spiral clean. PPE: cut-resistant sleeves were issued for jam clearing. The engineering changes did most of the work; the procedure and PPE backed them up.

3. Provide and maintain equipment, materials and protective devices

The employer must provide and maintain equipment, machines, devices and materials in a condition that is safe, and must provide the protective equipment the work requires. Maintenance is part of the duty: a guard that was safe when installed but has since been damaged is no longer compliant. The duty includes inspecting equipment, fixing defects promptly, removing defective equipment from service, and following manufacturer instructions. In Nova Scotia, employers must generally provide required protective equipment, although some items may be supplied by workers by agreement.

4. Inform, instruct and train

The Act requires employers to provide the information, instruction, training and supervision necessary to protect workers, and to make sure workers know about the hazards of their work. Training must be specific to the job and the equipment, delivered in a way the worker understands, refreshed when things change, and checked for effectiveness. Nova Scotia's regulations add specific training requirements for many hazards, including WHMIS for hazardous products, fall protection, first aid and harassment prevention.

The spiral conveyor investigation found that the injured worker had attended annual lockout training. But the training was a classroom video covering lockout in general, not the specific disconnects, procedures and verification steps for the machines his crew actually cleaned. He knew the rule; he had never been shown how to follow it in the two and a half hours the schedule allowed. Training that does not match the job does not meet the duty.

5. Supervise competently

Nova Scotia's Act requires employers to provide competent supervision. A competent person, in the Act's sense, is someone qualified by knowledge, training and experience to do the assigned work safely, who knows the law that applies to the work and the hazards involved. Lesson 4 looks at what this means for supervisors. For employers, the duty is to choose supervisors carefully, train them in their legal duties and the hazards they oversee, give them time and authority to supervise, and check that they are doing it.

6. Involve workers

Nova Scotia employers must establish a joint occupational health and safety committee where 20 or more workers are regularly employed, or have a health and safety representative where there are between 5 and 19, must cooperate with them, and must respond in writing within 21 days to written recommendations. Employers with 20 or more workers must also have a written occupational health and safety program, and those with 5 or more a written policy. These are not just paperwork requirements: they are the legal machinery of the internal responsibility system.

7. Respond to incidents and emergencies

Employers must have emergency procedures, provide first aid, report serious incidents to the Department within the time limits, preserve the scene when required, investigate, and correct what caused the incident. Lesson 10 covers the reporting rules in detail. The investigation duty is about learning: finding why the incident happened at every level, not just who was holding the tool.

8. Comply, and make sure others comply

Finally, the employer must comply with the law and make sure its supervisors and workers comply. That means having rules, communicating them, checking that they are followed, and responding consistently when they are not. A rule that is routinely broken with supervisors' knowledge is, in practice, not a rule at all, and courts and regulators treat it that way.

Turning duties into a checklist

Elena turned the eight duties into a simple self-assessment for each department. Supervisors scored each duty from 0 (not in place) to 3 (in place, documented and verified), and the scores were reviewed with the plant manager. The point was not the score but the conversation about the gaps.

# Self-assessment of employer duties for night sanitation, before and after changes (0 to 3).
duties = ["identify hazards", "control hazards", "equipment", "train and inform",
          "supervise", "involve workers", "respond to incidents", "comply and enforce"]
before = [1, 1, 2, 1, 0, 1, 2, 0]
after  = [3, 3, 2, 3, 2, 2, 3, 2]
print(f"{'duty':<22}{'before':>7}{'after':>7}")
for d, b, a in zip(duties, before, after):
    flag = "  <- still a gap" if a < 3 else ""
    print(f"{d:<22}{b:>7}{a:>7}{flag}")
print(f"{'total (max 24)':<22}{sum(before):>7}{sum(after):>7}")

duty                   before  after
identify hazards            1      3
control hazards             1      3
equipment                   2      2  <- still a gap
train and inform            1      3
supervise                   0      2  <- still a gap
involve workers             1      2  <- still a gap
respond to incidents        2      3
comply and enforce          0      2  <- still a gap
total (max 24)              8     20

The before scores showed where the system had failed: supervision and enforcement scored zero because the previous supervisor had tolerated skipped lockout, and training and hazard assessment scored one because they described work as imagined. The after scores showed progress but also honest gaps. Equipment stayed at two because older machines still had disconnects in awkward places, and worker involvement at two because the night crew had only just started sending a member to the committee.

Duties to people who are not employees

The general duty covers persons at or near the workplace, not just employees. That includes contractors, visitors, delivery drivers, customers, students on work placements and members of the public walking past. For Harrowgate Foods Ltd., the duty to non-employees showed up at the loading docks, where truck drivers from carriers waited in the yard while forklifts moved, and in the plants, where food safety auditors, equipment technicians and cleaning contractors worked alongside employees. The employer's duty to them is the same in principle: identify the hazards they face, control them, and give them the information they need, such as a visitor orientation and marked walkways.

Duties that cannot be delegated

Employers often hire consultants, contractors and staffing agencies to help with safety. That is sensible, and the law expects employers to use expertise they do not have in-house. But the core duty cannot be handed off. If a consultant writes the lockout program and it is wrong, the employer still answers for it. If a contractor performs maintenance unsafely in the employer's plant, the employer may still be responsible for failing to coordinate and check. Elena's rule for Harrowgate Foods Ltd. was that every contractor and consultant could advise and help, but a named Harrowgate Foods Ltd. manager always owned each hazard and each control.

Resources and time are part of the duty

One finding from the spiral conveyor investigation changed how Rachel talked to the leadership team. The night crew had the training, the procedure and the locks. What they did not have was time. When a company sets a schedule that cannot be met without skipping a safety step, it has created the hazard as surely as if it had removed the guard. Courts and regulators look at whether the employer gave people the resources, staffing and time needed to work safely, not only at whether the rules existed on paper. Rachel added a line to the one-page list: 'If we set the target, we own the trade-offs it forces.'

Dev took that line seriously. When the bakery planned to add a fourth bread variety to the morning run, he asked how the extra changeover would affect the sanitation window before the change was approved, and the schedule was adjusted in advance instead of after a near miss. Asking that question early is part of what competent supervision looks like, and it is the subject of the next lesson.
