Safety Data Sheet (SDS) for Hydrochloric Acid

This Safety Data Sheet (SDS) provides comprehensive information regarding the hazards, safe handling procedures, and emergency response guidelines for hydrochloric acid. It is crucial to understand this information to ensure the safety of workers and the environment.

Identification

The SDS includes the product identifier, other means of identification (e.g., synonyms), recommended use, restrictions on use, and supplier information, including name, address, and emergency phone number. [3]

Hazard Identification

This section details the hazard classification of hydrochloric acid, including the class, category, or subcategory. It also includes label elements such as symbols, signal words, hazard statements, and precautionary statements. Other hazards not resulting in classification are also described. [3]

Composition/Information on Ingredients

This section includes the chemical name, common name and synonyms, CAS registry number, and chemical name of impurities, stabilizing solvents, and/or additives when the hazardous product is a material or substance. For each material or substance in a mixture that is classified in a health hazard class, the chemical name, common name and synonyms, CAS registry number, and concentration are provided. [2]

First-Aid Measures

This section describes first-aid measures by route of exposure (inhalation, skin contact, eye contact, and ingestion), the most important symptoms and effects (acute or delayed), and the need for immediate medical attention and special treatment. [2]

Fire-Fighting Measures

This section specifies suitable and unsuitable extinguishing media, specific hazards arising from the hazardous product (e.g., hazardous combustion products). [2]

Accidental Release Measures

For non-emergency personnel and emergency responders, this section details protective equipment and emergency procedures. It also covers environmental precautions and methods and materials for containment and cleaning up spills, including reference to other relevant sections. [8] [8] [8] [8]

Handling and Storage

This section outlines precautions for safe handling, including hygiene measures, and conditions for safe storage, including any incompatibilities and storage temperature. [8] [8]

Exposure Controls/Personal Protection

This section specifies control parameters, appropriate engineering controls, and individual protection measures/personal protective equipment, including hand, eye, and skin protection. [8] [8] [8]

Physical and Chemical Properties

This section details various physical and chemical properties such as partition coefficient, vapor pressure, density, relative density, relative vapor density, and particle characteristics. [1] [1] [1] [1] [1]

Stability and Reactivity

This section covers reactivity, chemical stability, possibility of hazardous reactions, conditions to avoid (e.g., static discharge, shock, or vibration), incompatible materials, and hazardous decomposition products. [1] [1] [1] [1] [1] [1]

Toxicological Information

This section provides a concise but complete description of the various toxic health effects and the data used to identify those effects, including information on likely routes of exposure, symptoms, and delayed/immediate/chronic effects. Numerical measures of toxicity, including acute toxicity estimates (ATEs), are also included. [1]

Ecological Information

This section includes ecotoxicity, persistence and degradability, bioaccumulative potential, mobility in soil, and other adverse effects. [1]

Disposal Considerations

This section provides information on safe handling for disposal and methods of disposal, including any contaminated packaging. [1]

Transport Information

This section includes the UN number, UN proper shipping name, transport hazard class(es), packing group, environmental hazards, and special precautions. [6]

Regulatory Information

This section specifies safety, health, and environmental regulations specific to the product. [6]

Other Information

This section includes the date of the latest revision of the SDS. [6]

Availability of SDS

Suppliers must provide the SDS in both English and French, either as one bilingual SDS or as two separate SDSs. Employers must ensure that all hazardous products have an up-to-date SDS readily available to workers and the health and safety committee. [7] [4]

SDS Updates

The SDS must be updated within 90 days when significant new information becomes available that changes the product's classification or protective measures. Employers should actively seek updated SDSs, and if aware of significant new information, must add it to the existing SDS. [4] [5]
