Risk matrix 5×5 (before and after controls)
Score a hazard by likelihood and severity, then score it again with the planned controls in place, and see whether the remaining risk is acceptable.
CalculatorInjury frequency and severity rates (LTIFR, TRIR, DART)
Turn injury counts and hours worked into rates you can compare across months and sites, with the two common rate bases shown side by side.
CalculatorDaily noise exposure (dose and LEX,8h)
Add up the noise levels a worker meets during the shift and the time at each, and get the daily dose against the criterion you choose, plus the 8-hour equivalent level.
CalculatorHeat stress check (WBGT vs NIOSH RAL / REL)
Calculate the WBGT from your three thermometer readings, adjust for clothing, and compare it with the NIOSH limit for the metabolic rate of the work.
CalculatorManual lifting check (Revised NIOSH Lifting Equation)
Enter the lift geometry and frequency to get the recommended weight limit for a two-handed lift and the lifting index for the actual load.
CalculatorPPE matrix and stock planner
List tasks or areas, mark the PPE each one needs after higher controls, and get the number of people needing each item so you can plan issue and stock.
ChecklistHierarchy of controls review
Check a hazard against each level of the hierarchy, from elimination down to PPE, before you accept the controls in a risk assessment.
ChecklistIncident investigation checklist
Work through an incident or serious near miss from making the scene safe to closing the actions, looking for system causes rather than blame.
ChecklistSafety inspection walk
A planned walk of one area covering housekeeping, access, machinery, electrical, chemicals and emergency equipment.
ChecklistSafety observation card
Watch a task for a few minutes, note safe and at-risk actions, then talk with the person about it.
ChecklistNear-miss report
Record an event that could have hurt someone, the quick fix and whether it needs a deeper look.
ChecklistWorking at height pre-task check
Check before work at height: can it be avoided, is the access equipment right and inspected, are fall prevention and rescue in place.
ChecklistConfined space entry check
Check before anyone enters a tank, pit, vessel or duct: avoid entry if possible, isolate, test the atmosphere, attendant and rescue ready.
ChecklistContractor safety induction
Cover the site rules, hazards, emergency arrangements and permits with every contractor before they start work.
ChecklistHot work permit check
Check before welding, cutting, grinding or brazing: combustibles cleared, fire watch in place, and the area checked after the work.
ChecklistFire safety inspection
A monthly round of extinguishers, alarms, exits, emergency lighting and fire doors in one building or area.
ChecklistEvacuation drill record
Plan, run and review an evacuation drill: scenario, timing, roll call and lessons.
BoardSafety KPI dashboard
Leading and lagging safety indicators on one board, with the actions that move them.
BoardSafety committee meeting
A monthly meeting of managers and worker representatives: review incidents, inspections and actions, and agree decisions.
BoardAnnual HSE plan board
The year's HSE objectives and programmes as cards, moved from planned to done, with a few KPIs to show progress.
BoardToolbox talk board
A 5–10 minute safety talk at the start of work: one topic, questions from the team, and actions from what they raise.
Environment & waste tools
Role guides: Environmental officer
GHG inventory, Scope 1 and 2
List fuels burned on site (Scope 1) and purchased electricity or heat (Scope 2), each with its emission factor, and get tonnes of CO2e by scope and by source.
CalculatorWater consumption and intensity tracker
Enter monthly water use and output, and see total use, water per unit and the change from the first months to the last.
CalculatorEnvironmental aspects and impacts register
List activities, their environmental aspect and impact, score severity and likelihood, and flag the significant aspects that need controls and objectives.
CalculatorWaste register and diversion rate
Record each waste stream with its quantity, whether it is hazardous and where it goes, and get the total, hazardous share and the share diverted from disposal.
CalculatorChemical inventory and SDS review register
List chemicals on site with the date of their safety data sheet and whether they are hazardous, and see which sheets are due for review.
ChecklistSpill response check
Check that spill kits, bunds and drain covers are ready, and walk through the first actions for a chemical or oil spill.
BoardEnvironmental KPI board
Waste, water, energy and complaints on one board with the actions that improve them.
