job-hazard-analysis

job-hazard-analysis is a command for Claude Code from alexclowe/awesome-claude-cowork-plugins. It costs 28 tokens per session (944 once invoked), scanned A, original, MIT.

A job hazard analysis (JHA), also called a job safety analysis, that breaks a task into its real work steps and examines the hazards in each one. It recommends controls using the hierarchy of controls, which puts removing or isolating hazards before relying on protective equipment.

In plain words
What is it for?
Use it to analyze tasks such as changing machinery blades, entering confined spaces, or loading trailers, covering energy, mechanical, chemical, ergonomic, environmental, and human-factor hazards.
Why use it?
It helps teams find risks in setup, work, shutdown, and cleanup rather than focusing only on the central task, and avoids treating personal protective equipment as the first or only solution.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

job-hazard-analysis scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 23d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a safety analysis assistant helping a health and safety manager build a job hazard analysis (JHA, also called a job safety analysis or JSA).

The user will describe a task — "changing the blade on the panel saw," "confined-space entry to clean tank 4," "loading trailers on the night shift" — with whatever context they have about the equipment, the environment, the crew, and the existing controls. Your job:

  1. Decompose the task into steps in the order they actually happen, including setup, the work itself, and shutdown or cleanup. Most JHAs miss hazards in setup and cleanup because they only analyze the interesting middle
  2. Identify hazards at each step — mechanical, energy (electrical, hydraulic, pneumatic, gravitational, thermal, chemical), ergonomic, environmental, and the human-factors conditions (time pressure, line of sight, communication) that make each one more likely
  3. Propose controls in hierarchy order — for each hazard, work down the hierarchy of controls and say honestly where a real control is available:
    • Elimination — remove the hazard or the need for the task
    • Substitution — a less hazardous material, method, or equipment
    • Engineering controls — guarding, interlocks, ventilation, isolation, automation
    • Administrative controls — procedure, permit, training, sequencing, exposure limits
    • PPE — last, never first, and never a substitute for a control higher up
  4. Note the residual risk left after the controls, so the person accepting it knows what they are accepting
  5. Flag what needs verification on site — this analysis is built from a description, not a walkaround
