About MSDS Lookup
The SDS/MSDS Reference is a comprehensive, searchable guide for chemical safety professionals, EHS managers, and laboratory personnel who need quick access to Safety Data Sheet interpretation guidelines. It covers all 16 SDS sections in detail: from Section 1 (product identification and emergency contacts) through Section 16 (revision history), including hazard identification with GHS classification, composition thresholds (0.1% for carcinogens, 1.0% for other health hazards), first-aid measures by exposure route, fire-fighting procedures, and accidental release response.
The GHS pictogram section provides detailed coverage of all nine hazard pictograms (GHS01 through GHS09) with their applicable hazard categories, signal words, and corresponding H-statement codes. Exposure limit entries explain TLV-TWA (8-hour time-weighted average), TLV-STEL (15-minute short-term), PEL/OEL legal limits, and IDLH values with real chemical examples (toluene, formaldehyde, benzene, hydrogen sulfide). The PPE section covers respirator selection by exposure level (particulate N95/FFP2, chemical cartridge color codes, SCBA for IDLH), glove material compatibility (nitrile, neoprene, butyl, PVA, Viton), and eye/face protection standards.
The reference also includes complete H-statement listings for physical hazards (H200-H290) and health hazards (H300-H373), P-statement prevention and response codes (P200-P300 series), UN dangerous goods classification (9 classes with subdivisions), packing group criteria (PG I/II/III based on flash point, LD50, and corrosivity), and a segregation/incompatibility table for safe chemical storage and transport. All entries are searchable by keyword and organized into six categories.

Frequently Asked Questions
What are the 16 sections of a Safety Data Sheet (SDS)?
The SDS follows the GHS/CLP 16-section format: 1) Identification, 2) Hazard Identification, 3) Composition, 4) First-Aid, 5) Fire-Fighting, 6) Accidental Release, 7) Handling/Storage, 8) Exposure Controls/PPE, 9) Physical/Chemical Properties, 10) Stability/Reactivity, 11) Toxicology, 12) Ecology, 13) Disposal, 14) Transport, 15) Regulatory, 16) Other Information.
What do the GHS pictograms mean?
GHS01 (exploding bomb) = explosives; GHS02 (flame) = flammables; GHS03 (flame over circle) = oxidizers; GHS05 (corrosion) = corrosives and serious eye damage; GHS06 (skull) = acute toxicity Cat.1-3; GHS07 (exclamation) = irritants and acute toxicity Cat.4; GHS08 (health hazard) = carcinogens, mutagens, reproductive toxins; GHS09 (environment) = aquatic toxicity.
What is the difference between TLV-TWA and TLV-STEL?
TLV-TWA is the 8-hour time-weighted average concentration below which nearly all workers can be exposed daily without adverse effects (e.g., toluene 20 ppm). TLV-STEL is the 15-minute short-term limit, allowing brief peak exposures above TWA (maximum 4 times per day, 60 minutes apart). If no STEL is set, the excursion limit is generally TWA x 3.
How do I select the right chemical-resistant gloves?
Match glove material to the chemical: Nitrile for alcohols, oils, and acids; Neoprene for acids, alkalis, and alcohols; Butyl rubber for ketones, esters, and aldehydes; PVA for aromatics and halogenated solvents (but not water); Viton for aromatics, halogenated, and aliphatic solvents. Always check the breakthrough time for your specific chemical-glove combination.
When is a supplied-air respirator (SCBA) required instead of a cartridge respirator?
SCBA or supplied-air respirators are required in IDLH (Immediately Dangerous to Life or Health) environments, oxygen-deficient atmospheres (O2 below 19.5%), and when the contaminant identity is unknown. Chemical cartridge respirators are only suitable when the contaminant is identified and concentrations are below IDLH levels.
What are H-statements and P-statements?
H-statements (Hazard) describe the nature and severity of hazards: H200-H290 for physical hazards (explosives, flammables, oxidizers), H300-H373 for health hazards (toxicity, irritation, carcinogenicity). P-statements (Precautionary) provide safety advice: P200 series for prevention (P280: wear PPE), P300 series for response (P301+P310: if swallowed, call poison center).
How are UN dangerous goods classified for transport?
The UN system has 9 hazard classes: Class 1 (Explosives), Class 2 (Gases: 2.1 flammable, 2.2 non-flammable, 2.3 toxic), Class 3 (Flammable liquids), Class 4 (Flammable solids), Class 5 (Oxidizers/organic peroxides), Class 6 (Toxic/infectious), Class 7 (Radioactive), Class 8 (Corrosives), Class 9 (Miscellaneous). Packing groups (I/II/III) indicate danger severity.
Which chemicals must never be stored together?
Key prohibited combinations include: oxidizers (5.1) with flammable liquids (3) or solids (4.1); acids (8) with alkalis (8) due to exothermic reactions; acids with cyanides (6.1) which releases HCN gas; oxidizers with organic peroxides (5.2); and water-reactive materials (4.3) with aqueous solutions. Maintain minimum 3m separation with fire walls between incompatible groups per NFPA 400.
