Building a case for prevention

Lesson objectives

Apply building a case for prevention to the case, justify the decision and state its limits and test.

A case for improvement does not begin and end with an injury count. Serious exposure can exist before anyone is hurt; a near miss may reflect luck rather than an effective control. First reconstruct the work: who is exposed, to what source of harm, during which task, how often, and under which existing control? Check evidence that the control is actually used. Then describe a credible harm pathway if it fails. This turns a vague appeal to “safety” into a decision that a manager can test.

The moral case concerns preventing foreseeable harm to workers and others affected by the work. It is not a price placed on a person. If two workers clear machine jams while it can still start, the duty to care does not wait for an injury. The financial case describes possible lost production, replacement labour, repair, investigation, absence and damaged confidence. Separate recorded costs from estimates and give a range when data are incomplete; a precise invented total misleads. Insurance may cover some costs, but it does not remove disruption, harm or professional responsibility.

The regulatory case needs a defined scope. The GIC syllabus addresses ILO Convention C155, Recommendation R164 and enforcement, but an international instrument does not automatically state the domestic law of every workplace. Record the country, activity and competent regulator, then check the current local text before claiming that a specific measure is legally mandatory. Where that check has not been completed, recommend controlling the hazard and verifying compliance without declaring a particular breach. A management certificate or completed training course is no substitute for an effective field control.

Frame the decision in four fields: established fact, harm pathway, proposed control and evidence of effectiveness. Prefer a measure that removes or isolates exposure where practicable, and name an owner and a verification date. Do not use incident cost to justify personal protective equipment alone if energy isolation or process change can remove exposure. When evidence is incomplete, start with a safe inspection and preserved records rather than assuming low risk. A sound memo asks for a specific decision and states its limits: illustrative figures are not precise probabilities, and local legal review is separate from occupational risk analysis.

Example

Hypothetical training scenario in Jeddah: at a fictional packing workshop, two workers report three jams in one week. In one event a worker reached towards a moving roller after a guard had been lifted; no injury occurred. The record has no verified financial cost and shows that the routine stop does not isolate energy before a jam is cleared. The task is a short decision memo, not a claim about a particular breach of Saudi law.

Inputs: three jams, one hand near a roller, a lifted guard, and a stop that does not isolate energy. Steps: (1) State the harm pathway: unexpected movement during access could cause a crush or cut injury. (2) Separate the reasons: prevent foreseeable harm; recognise possible disruption, repair and absence without inventing a sum; check local requirements separately. (3) Compare controls: a warning alone relies on behaviour, whereas fixing the cause of jams and verifiable energy isolation reduce exposure. (4) Specify action: the supervisor stops the present jam-clearing method, assigns a competent person to review guarding and isolation before the task resumes, then checks workers' understanding and records the result.

Output and decision: commission an engineering review of the jam cause and guard, with energy isolation before any jam is cleared; do not settle for a warning poster. Closure criteria are a safely observed trial after isolation, confirmation that the machine cannot start at the access point, and a named owner and date. Limits: this is fiction; the count is not a statistical risk rate or a local legal determination, and the precise isolation method requires examination of the actual equipment by a competent person.

Exercise

At a fictional food plant, a supervisor records four oil spills beside a transfer route over two weeks. Workers wiped the floor each time; one worker slipped without injury. A container sits below a pipe with moisture around a joint, and the joint has no maintenance record. Write four fields: fact, harm pathway, immediate and root controls, and closure evidence. Add one moral and one financial sentence without inventing amounts, and state what is needed before any legal assertion. Expected output: a 120–180 word decision memo. First-attempt time: 15 minutes to write and 5 minutes to compare with the solution.

Check your answer

Inputs: four spills, one slip without injury, moisture at a joint, a container below it, and no maintenance record. Method: treat recurrence as evidence of exposure, not lack of injury as proof of low risk. Trace the pathway: oil reaches the walking route, reduces grip and can cause a fall. Isolate or divert the route and clean the spill immediately as interim controls; have a competent person inspect and repair the source, then verify that the leak does not recur. Output memo: “I recommend closing the contaminated section and cleaning it now, then inspecting and repairing the joint before restoring ordinary access. This prevents foreseeable harm and may reduce disruption, cleaning and absence without asserting a calculated cost. Maintenance should record the cause and test result; the supervisor should observe the route during subsequent operation. Close the action only after a documented check shows that the joint and floor remain dry. Check the applicable local text and regulator before calling this a legal violation.” Decision and limit: the container and wiping do not address the source; moisture near the joint is a lead to investigate, not conclusive proof that this joint alone caused the oil.

Lesson summary

Building a case for prevention: connects case evidence with a worked decision and an independent practice task.
