How to Use This Calculator

Work through each safety category in the audit checklist.
Enter a compliance score (0-100%) for each area: PPE, chemical storage, emergency equipment, waste disposal, and training.
Set the weighting for each category based on regulatory priority.
Review the overall audit score and identify categories below the passing threshold.
Create corrective action items for any category scoring below 80% to improve compliance.

How the result changes with Chemical hygiene (0-10)

PPE compliance (0-10): Personal protective equipment availability and proper use (gloves, goggles, lab coats).
Chemical hygiene (0-10): Chemical labeling, SDS availability, storage compatibility, and chemical hygiene plan adherence.
Fire safety (0-10): Fire extinguisher access, clear exits, flammable storage limits, and fire alarm function.
Fume hood operation (0-10): Fume hood face velocity (80-120 fpm), sash height, certification status, and proper use.
Waste management (0-10): Waste segregation, container labeling, accumulation limits, and disposal schedule.
Emergency equipment (0-10): Eyewash stations, safety showers, spill kits, and first aid — tested and accessible.
Housekeeping (0-10): Bench cleanliness, no clutter in aisles, organized storage, and proper food/drink policies.
Electrical safety (0-10): No daisy-chained power strips, GFCI near water, equipment cords in good condition.

Overall weighted score (/100): Weighted safety audit score (0-100). Critical categories weighted more heavily.
Risk level (1-5): 1=Excellent, 2=Good, 3=Acceptable, 4=Needs improvement, 5=Critical.
Compliance rate (%): Percentage of categories scoring 7/10 or above (passing threshold).
Critical categories (<5): Number of categories scoring below 5/10 (immediate action required).
Warning categories (5-6.9): Number of categories scoring 5-6.9/10 (improvement needed).
Passing categories (≥7): Number of categories meeting or exceeding the 7/10 threshold.
Lowest category score: Score of the weakest safety category — priority for improvement.
Highest category score: Score of the strongest safety category.
Score range: Difference between highest and lowest category scores. Large range suggests inconsistency.
Simple average (/100): Unweighted average of all category scores for comparison.
Improvement gap (%): Percentage improvement possible from current score to perfect 100.
