2. Statutory Sanitary Ratios: The Mathematical Formula for Toilets & Basins

Under Regulation 2 and the statutory schedules, sanitary facilities must be strictly gender-segregated, completely enclosed with lockable doors, and supplied with toilet paper, soap, and clean hand-drying towels or electric warm-air dryers.

The law establishes a strict mathematical ratio based on the maximum number of employees of each sex working on shift simultaneously.

Furthermore, under SANS 10400-S, where ten or more employees work, the employer must provide at least one dedicated Wheelchair-Accessible Universal Toilet Facility fitted with grab rails, outward-opening doors, and emergency pull-cords.

3. Change Rooms, Hot Showers & Double-Locker Systems for Dirty Trades

Under Regulation 4, where employees must change into specialized protective workwear, the employer must provide separate Male and Female Change Rooms directly accessible without passing through production areas.

Where employees are exposed to toxic chemical agents (HCA), asbestos, lead, pesticide spraying, biological agents, or heavy dirt/grease, the change room must feature Hot and Cold Water Showers (minimum 1 shower per 15 workers) and Double-Compartment Clothes Lockers.

The double-locker system physically separates contaminated work overalls from clean personal street clothing, preventing workers from carrying toxic chemical dusts home to their families and cars. Change rooms must be naturally or mechanically ventilated with at least 6 air changes per hour.

4. Dining Areas, Food Hygiene & SANS 241 Potable Drinking Water

Dining Rooms (Regulation 5): Where employees work with hazardous chemical or biological substances, they are legally prohibited from eating, drinking, or storing food at their workstations. The employer must provide a dedicated, hygienic, well-ventilated Dining Room / Canteen equipped with tables, chairs, food refrigeration, and handwash sinks.

Potable Drinking Water (Regulation 7): Employers must provide an adequate, continuous supply of free Potable Drinking Water complying with SANS 241, situated within 100 metres of every workstation. If water is sourced from commercial boreholes or rainwater harvesting tanks, microbiological and chemical water testing must be conducted annually by a SANAS-accredited laboratory.

5. 5-Stage Facilities Design, Ratio Verification & Maintenance Roadmap

01
Audit Workplace Headcounts & Gender Shift Schedules

Calculate maximum shift headcounts for male and female workers across all operational shifts.

02
Verify Sanitary Fixture Ratios Against Statutory Schedule

Audit existing toilets, urinals, and washbasins; install additional plumbing fixtures where deficits exist per SANS 10400-P.

Construct Gender-Segregated Change Rooms with Double Lockers

Install ventilated male/female change rooms with hot showers and two-compartment lockers for dirty trades.

05
Verify SANS 241 Drinking Water & Maintain Daily Cleaning SOPs

Test borehole/municipal drinking water annually, position water coolers <100m from staff, and execute daily cleaning.
