Risk Management: Identifying and Preventing Workplace Hazards

Occupational Safety and Health Act, Chap. 88:08

Why This Matters

Risk management is the systematic process of identifying the hazards present in the workplace, assessing the likelihood and severity of harm they could cause, and putting in place controls that reduce that risk to an acceptable level. It is the operational heart of the employer’s duty of care under the OSH Act and the discipline that, more than any other, determines whether a workplace is genuinely safe or merely compliant on paper.

A hazard is anything with the potential to cause harm, a wet floor, a faulty electrical connection, a poorly designed workstation, a chemical substance, a pattern of excessive workload, or a relationship between employees that has deteriorated to the point of psychological risk. A risk is the likelihood that the hazard will actually cause harm, and the severity of that harm if it does. The purpose of risk assessment is to bridge the gap between identifying a hazard and implementing a control, to ensure that the response to the hazard is proportionate to the actual risk it presents.

Common Workplace Hazards in T&T

While every workplace has its own specific hazard profile, the following categories are encountered consistently across industries in Trinidad and Tobago.

Hazard Category	Common Examples	Industries Most Affected
Physical Hazards	Slips, trips and falls · Working at height · Manual handling injuries · Noise exposure · Extreme heat	Construction · Hospitality · Retail · Manufacturing · Energy
Chemical Hazards	Cleaning products · Lubricants · Solvents · Pesticides · Hazardous substances in production	Manufacturing · Agriculture · Cleaning services · Energy
Ergonomic Hazards	Repetitive strain · Poor workstation design · Prolonged sitting · Awkward postures	Office environments · Retail · Manufacturing · Healthcare
Biological Hazards	Exposure to blood-borne pathogens · Infectious disease · Insect exposure · Mould	Healthcare · Food service · Outdoor work
Psychosocial Hazards	Workplace stress · Harassment and bullying · Excessive workload · Job insecurity · Shift work	All industries · Particularly high-pressure or understaffed environments
Environmental Hazards	Inadequate ventilation · Poor lighting · Extreme temperatures · Hurricane-related risks	All industries

The Risk Assessment Process

A risk assessment follows a defined five-stage process. Each stage must be documented. An undocumented risk assessment provides no evidence that the employer has met their duty of care and cannot be produced in response to an OSH inspection or a legal proceeding.

1. Identify the Hazards

Walk through the workplace systematically and identify everything that could potentially cause harm. Include input from employees, the people who work with the hazards every day are often the most reliable source of information about where the risks actually lie. Review incident and near-miss records to identify hazards that have already caused or almost caused harm. Consider hazards that arise not only from the physical environment but from the way work is organised, shift patterns, workload distribution, supervision levels, and the pace of work.

2. Assess the Risk

For each hazard identified, assess the risk it presents by considering two factors: the likelihood that the hazard will cause harm (rare, possible, or likely) and the severity of the harm if it does (minor injury, serious injury, or fatality). A risk matrix can be used to combine these two factors into an overall risk rating, low, medium, high, or critical. The risk rating determines the priority of the control measures required and the urgency with which they must be implemented.

	Minor Injury	Serious Injury	Fatality
Rare	Low	Medium	High
Possible	Medium	High	Critical
Likely	High	Critical	Critical

3. Apply the Hierarchy of Controls

Once the risk has been assessed, the employer must implement control measures to reduce it to an acceptable level. Controls should be selected by working through the Hierarchy of Controls, a framework that ranks control measures from most to least effective. The employer should always implement the highest-level control that is reasonably practicable before resorting to lower-level controls.

Control Level	Effectiveness	Description and Example
1: Elimination	Most Effective	Remove the hazard entirely from the workplace. This is the most effective control because it eliminates the risk at source. Example: remove a chemical that is no longer necessary for the process.
2: Substitution	High Effectiveness	Replace the hazard with something less dangerous. Example: replace a highly toxic cleaning product with a safer alternative that achieves the same result.
3: Engineering Controls	Moderate-High	Use physical measures to isolate people from the hazard. Example: install machine guards, improve ventilation, or redesign a workstation to reduce ergonomic strain.
4: Administrative Controls	Moderate	Change the way people work to reduce exposure. Example: rotate workers to limit exposure time, implement safe work procedures, or provide additional supervision in high-risk areas.
5: Personal Protective Equipment (PPE)	Least Effective	Provide protective equipment as a last line of defence. Example: safety boots, gloves, hard hats, hearing protection. PPE does not eliminate the hazard; it only reduces the consequences of exposure. It should never be the primary control.

4. Implement and Communicate the Controls

Selected control measures must be implemented promptly and communicated to all affected employees. A control measure that has been identified in a risk assessment but not yet implemented does not reduce the risk; it simply records that the employer knew about it. Assign a responsible person and a deadline for each control measure, and record both in the risk assessment document. Where the implementation of a permanent control will take time, consider interim measures that reduce the risk in the intervening period.

5. Monitor and Review

Risk assessments are not one-time exercises. They must be reviewed whenever there is a significant change to the work environment or process, whenever an incident or near-miss occurs that was not anticipated in the existing assessment, and at regular intervals as part of the workplace inspection programme. A risk assessment that was completed three years ago and never reviewed is not a compliance asset; it is a liability, because it demonstrates that the employer identified risks and then stopped monitoring them.

Practical Insight: Employer Risk The most common risk management failure in SMEs is the risk assessment that is completed once, filed, and never revisited. This typically occurs because the employer treats risk assessment as a documentation compliance exercise rather than a management tool. In practice, a risk assessment is only useful if it is current, if the controls it prescribes have actually been implemented, and if the person responsible for each control knows they are accountable for it. A quarterly review of the risk assessment register, even a brief one, conducted by the Safety and Health Committee or a designated safety officer, is sufficient to maintain the document as a live and useful tool rather than an archived record of good intentions.

Template – Risk Assessment Register

Use this register to document all risk assessments for the workplace. Each identified hazard should have its own entry. The register should be reviewed quarterly and updated whenever a new hazard is identified, a control measure is implemented or changed, or an incident occurs that was not covered by the existing assessment.
