4.3 Safety Data Sheets, Chemical Storage & First Aid
Key Takeaways
- A Safety Data Sheet (SDS) is a standardized 16-section document that describes a chemical product's hazards, safe handling, storage, and first-aid measures; employers are legally required to keep an SDS for every hazardous product in the salon, readily accessible to all employees
- Know the agency roles: OSHA covers worker hazards and hazard communication, EPA registers surface disinfectants, FDA regulates cosmetics and over-the-counter drug products, and the Tennessee Board regulates licenses and salon sanitation
- Store chemicals in their original labeled containers, tightly capped, in a cool dry location away from heat and sunlight; never mix products
- Chemical splashes in the eyes require immediate continuous flushing for at least 15 minutes or longer when the product label or SDS directs, followed by poison-control or medical guidance
- Control bleeding with gloved hands, clean gauze, and direct pressure; call 911 for uncontrolled bleeding, severe burns, breathing difficulty, or loss of consciousness
Salons handle chemicals every day — hair color, lighteners, relaxers, disinfectants, nail monomers, adhesives. Federal and state rules give salon workers a right to know about those hazards. OSHA governs workplace exposure, PPE, and hazard communication; the EPA registers surface disinfectants and approves their label claims; the FDA regulates cosmetics and over-the-counter drug products, though it does not preapprove most cosmetics; and the Tennessee Board governs licenses and shop sanitation.
Safety Data Sheets (SDS)
A Safety Data Sheet (SDS) is a standardized information document that manufacturers must provide for every hazardous chemical product. It replaced the older MSDS format when the United States adopted the Globally Harmonized System (GHS) of classification and labeling. Every SDS follows the same 16-section format, which is itself an exam fact. The sections you should recognize include:
- Identification of the product and manufacturer
- Hazard identification (including GHS pictograms and signal words)
- Composition / ingredients
- First-aid measures
- Firefighting measures
- Accidental release (spill) measures
- Handling and storage
- Exposure controls / personal protection (PPE such as gloves)
- Physical and chemical properties
- Stability and reactivity
- Toxicological information 12–16. Ecological, disposal, transport, regulatory, and other information
You do not need to memorize all sixteen by number, but know that first aid is Section 4, handling and storage is Section 7, and PPE guidance is Section 8 — those are the ones a working cosmetologist actually reaches for. The employer's obligation is clear and heavily tested: the salon must keep an SDS for every hazardous product on site and make the sheets readily accessible to every employee during every work shift. Locking them in the owner's office does not satisfy the rule.
GHS Hazard Pictograms
GHS labels use red-diamond pictograms that warn you at a glance:
| Pictogram | Meaning | Salon example |
|---|---|---|
| Flame | Flammable | Aerosol hairspray, nail polish remover (acetone) |
| Corrosion | Burns skin/eyes, corrodes metal | Relaxers, lighteners, some disinfectants |
| Skull and crossbones | Acute toxicity (harmful or fatal if swallowed/inhaled) | Certain professional chemical concentrates |
| Exclamation mark | Irritant, sensitizer, harmful | Hair color, adhesives |
| Health hazard | Long-term risks (respiratory sensitizer, carcinogen) | Nail monomer vapors, formaldehyde-containing products |
Safe Chemical Storage and Handling
Storage rules are common sense formalized, and the exam phrases them as rules:
- Keep every product in its original container with the original label — never pour chemicals into unmarked bottles or beverage containers.
- Keep containers tightly capped when not in use to prevent spills and evaporation.
- Store chemicals in a cool, dry, well-ventilated location away from heat, sparks, and direct sunlight — especially flammables like aerosols and acetone.
- Never mix products together unless the manufacturer directs it.
- Read the label and SDS before using a new product, not after an accident.
For spills: ventilate the area, put on gloves, absorb the spill with towels or absorbent material, and dispose of the waste per the product's SDS — do not rinse large chemical quantities down the drain unless the SDS says it is acceptable. Good ventilation at all times — local exhaust at manicure tables, open airflow for color services — reduces inhalation exposure, which is the most common chronic chemical risk in salons.
Basic Salon First Aid
| Accident | Correct first response |
|---|---|
| Cut with minor bleeding | Gloves on; apply clean gauze with direct pressure until bleeding stops; clean, apply antiseptic, bandage; clean and disinfect any blood-contaminated tools and surfaces |
| Chemical splash in the eye | Flush immediately with clean running water at an eyewash station or faucet for at least 15 minutes, or longer if the label or SDS directs; then obtain poison-control or medical guidance |
| Thermal burn (hot iron, hot wax) | Cool the area with cool running water; never apply ice, butter, or ointments; cover loosely; refer severe or blistering burns to a physician |
| Chemical burn (relaxer, lightener) | Remove the product immediately and flush skin with water; monitor and refer if damage continues |
| Allergic reaction (color, adhesive) | Stop the service, remove the product; for mild local reactions refer to a physician; for hives, swelling of face/throat, or breathing difficulty, call 911 |
| Fainting or dizziness | Lay the client flat, loosen tight clothing, ensure fresh air; call 911 if the client does not recover quickly |
When to call 911 versus refer to a physician: call 911 for uncontrolled bleeding, severe burns, difficulty breathing, chest pain, loss of consciousness, seizures, or signs of a severe allergic (anaphylactic) reaction. Refer to a physician — promptly but not by ambulance — for minor burns, persistent irritation, and any reaction that does not resolve quickly. Never diagnose; stabilize and escalate.
Prevention Rules That Avoid Claims
The cheapest accident is the one that never happens, and these habits protect both clients and your license:
- No eating or drinking at work stations — chemicals contaminate food, and crumbs contaminate products.
- Cap every bottle immediately after use.
- Unplug hot tools the moment you finish with them and rest them on heat-safe surfaces, never on towels or paper.
- Keep floors clear of cords, hair clippings, and spills to prevent slips.
- Perform a patch test before hair color services when the manufacturer requires it, and document it.
Why This Matters for the Exam
Exam questions in this area are highly factual: the SDS has 16 sections, employers must keep SDSs accessible, eye splashes are flushed immediately for the label- or SDS-directed period, and bleeding is controlled with gloves, gauze, and direct pressure. Pictogram identification and 911-versus-physician judgment round out the topic. Learn the table of accident responses above and you can answer nearly any first-aid scenario the exam constructs.
