Regulatory & Safety Interpretation

It seems the commercial cleaning industry is walking a dangerous tightrope where impeccable paperwork often masks a workplace where, despite near-universal fire safety training, a cleaner is statistically more likely to be injured by a rogue chemical, a wet floor, or their own untrained use of a shrieking vacuum than by an actual fire.
