Safe Work Practices and Permit-to-Work, Safety Communication, Behaviour-Based Safety and HSE Training/Induction
Permit to work
A PTW is a formal, documented authorisation for high-risk work: hot work, confined-space entry, electrical isolation, excavation, working at height, lifting, line breaking, radiography. It records the task, location, hazards, isolations, gas tests, precautions and the signatures of issuer and receiver. It is valid only for the stated task, place and period (usually one shift), must be displayed at the worksite, and is revalidated if conditions change or suspended on an alarm. Closure and handback matter as much as issue.
Isolation
LOTO: identify all energy sources, notify, shut down, isolate, lock and tag, release stored energy, then verify by attempting to start.
Communication
Toolbox talks before the shift, induction for everyone new to site, safety meetings, and the signage colour code: red prohibition, yellow warning, blue mandatory, green safe condition/first aid.
Behaviour-based safety
The ABC model: Antecedent → Behaviour → Consequence. Observers record safe and at-risk behaviour, give immediate constructive feedback and reinforce safe behaviour. BBS supplements - never replaces - engineering controls, and must not become a blame or discipline tool.
Training
Identify needs (TNA), deliver induction plus task and refresher training, verify competence, keep records, and evaluate at reaction, learning, behaviour and results levels. A toolbox talk is not competence training.
Traps
Treating a permit as a substitute for controls; confusing sign colours; describing BBS as punishment for unsafe acts; assuming attendance equals competence.
Rule of thumb
No permit, no work - for that task, that place, that time; and the person doing the job signs to confirm they understand it.
