Dangerous Goods Safety: GHS Pictograms, SDS Rules & Chemical Spill Response

3 Min Read

Hazardous materials and dangerous goods are present in virtually every industrial facility, warehouse, and maintenance department. Failure to properly classify, store, label, and handle hazardous chemicals exposes workers to catastrophic fire, chemical burns, asphyxiation, and long-term carcinogenicity.

Direct Safety Takeaway: Under OSHA’s Hazard Communication Standard (29 CFR 1910.1200 / GHS), every hazardous chemical must have a standardized 16-Section Safety Data Sheet (SDS), unambiguous manufacturer warning labels, and certified GHS pictograms. Never transfer chemicals into secondary containers without immediately applying an OSHA-compliant GHS secondary label.

The 9 Globally Harmonized System (GHS) Hazard Pictograms

GHS Pictogram Symbol	Hazard Category	Key Health / Physical Dangers
Flame	Flammables & Self-Heating	Flammable gases, liquids, aerosols, pyrophoric substances. (See Fire Prevention Guide).
Corrosion	Corrosives	Causes irreversible skin destruction, serious eye damage (wear ANSI Z87.1 splash goggles), and metal corrosion.
Skull and Crossbones	Acute Toxicity	Fatal or toxic in short-term exposure via inhalation, ingestion, or skin contact.
Health Hazard (Starburst Chest)	Chronic Health Hazards	Carcinogens, respiratory sensitizers, reproductive toxicity, target organ toxicity.
Exclamation Mark	Irritant / Skin Sensitizer	Harmful irritant, narcotic effects, acute toxicity (less severe).
Gas Cylinder	Compressed Gases	Liquefied, dissolved, or cryogenic gases under pressure (risk of rocket propulsion or explosion).
Exploding Bomb	Explosives	Self-reactive substances, organic peroxides, unstable explosives.
Flame Over Circle	Oxidizers	Releases oxygen, accelerating fires in combustible materials.
Environment (Fish & Tree)	Aquatic Toxicity	Acute and long-term aquatic environmental damage (EPA regulated).

The 16-Section Safety Data Sheet (SDS) Structure

When evaluating an unfamiliar chemical, frontline supervisors and technicians must consult the following priority sections on the standardized SDS:

Section 2 (Hazard Identification): Signal words (DANGER vs WARNING), hazard statements, and required pictograms.
Section 4 (First-Aid Measures): Immediate symptoms and emergency response protocols. (See First Aid Essentials).
Section 8 (Exposure Controls & Personal Protection): Permissible Exposure Limits (PELs) and required PPE specifications (respirators, glove materials).
Section 10 (Stability & Reactivity): Incompatible chemical families (e.g., never store acids with bases or oxidizers with flammables).

Chemical Spill Emergency Response: The SWIM Protocol

If an incidental chemical release occurs within your department, execute the SWIM protocol immediately:

S — Stop the Source: Only if safe and trained to do so (e.g., righting an overturned container or closing a valve while wearing proper PPE).
W — Warn Others: Notify coworkers in the immediate zone, alert the supervisor, and secure the perimeter.
I — Isolate the Area: Evacuate non-essential personnel and eliminate nearby ignition sources.
M — Mitigate with Spill Kits: Deploy chemical absorbent socks, pads, and neutralizers from designated spill response stations.

5-Minute Safety Talk / Toolbox Topic: Secondary Container Labeling

Meeting Question: “What must you do if you transfer solvent or degreaser from a 55-gallon drum into a spray bottle or small container?” (Answer: Immediately affix a secondary GHS label identifying chemical name and hazards).
Discussion Topic: “Where is our facility SDS master binder located, and how do you access electronic SDS sheets on mobile?”
Supervisor Reminder: “Never store chemicals in unlabeled drink bottles or food containers—this is an extreme poisoning hazard.”

Chemical Storage & HazCom Audit Checklist

☐ All primary and secondary chemical containers clearly labeled with GHS pictograms and signal words.
☐ SDS library complete, indexed, and accessible to all shifts without password barriers.
☐ Incompatible chemicals separated by physical distance or approved spill containment berms.
☐ Flammable liquids stored in UL-listed yellow flammable safety cabinets.
☐ Chemical spill response kits stocked with neutralizers, pads, and disposal bags.
☐ Eyewash stations and safety showers inspected weekly with flow testing verified.

Frequently Asked Questions

What is the difference between “Danger” and “Warning” on GHS labels?

Under GHS standards, DANGER indicates severe hazard categories (higher risk of fatal injury or severe explosion), while WARNING is used for less severe hazard categories.
