Chemical Handling & Safety: the full procedure

Keep an SDS for every product, follow label dilution and PPE, never mix chemicals, and label and store all containers safely.

• Applies to: All cleaners & janitorial staff.
• Frequency: Every shift / before every chemical use.
• Scope: Covers safe handling, dilution, labeling, and storage of cleaning chemicals. All chemical-hazard specifics defer to the product SDS, the manufacturer label, and OSHA Hazard Communication 1910.1200.

What you need

• Product SDS binder
• Manufacturer labels
• Gloves & eye protection
• Labeled secondary spray bottles
• Dilution measuring cup

The procedure, step by step

1. Read the label & SDS first — Before using any product, read its label and locate its Safety Data Sheet in the SDS binder to confirm hazards, PPE, and first-aid steps.
2. Wear the required PPE — Put on the gloves, eye protection, and any other PPE the label and SDS specify for that product — do not improvise.
3. Follow label dilution exactly — Mix concentrates only to the ratio on the label using a measuring cup; never eyeball, over-strengthen, or "double up" for tougher jobs.
4. NEVER mix chemicals — Never combine products — bleach plus ammonia (or other cleaners) creates toxic chloramine and chlorine gas that can cause severe lung damage or death.
5. Label every secondary bottle — Any spray bottle or refill container must carry the product identifier and a hazard warning per OSHA 1910.1200(f)(6); never leave a filled bottle unlabeled.
6. Use in ventilated areas — Open doors or run ventilation when using strong products, and never spray near another worker who may inhale fumes.
7. Store properly & separated — Return products to their assigned, ventilated storage area with caps closed; keep incompatible chemicals (e.g. bleach and acids/ammonia) apart per the SDS.
8. Respond to spills & exposure — For a spill or skin/eye contact, follow the SDS first-aid and cleanup instructions immediately and report it to your supervisor.

Quality check before you finish

• An SDS is on file and accessible for every product in use.
• All spray/secondary bottles labeled with product name and hazard.
• Dilution matches the label ratio (measured, not guessed).
• Correct PPE worn for each product.
• No two products combined at any point.
• Caps closed and products stored in assigned, separated locations.
• Any spill or exposure reported same shift.
