Keywords

💡Safety Data Sheets (SDS)

Safety Data Sheets, known as SDS, are critical documents in a laboratory setting, providing essential information about the properties, hazards, and safety precautions of chemicals. They are required for every chemical and are usually supplied by the manufacturer. In the script, it is emphasized that knowing the location of SDS in the lab and reviewing them before handling a chemical for the first time is crucial for safety.

💡Globally Harmonized System (GHS)

The Globally Harmonized System of Classification and Labeling of Chemicals, or GHS, is an international standard for the communication of chemical hazards. It is mentioned in the script as the system that dictates the format for safety data sheets, ensuring consistency in how chemical hazards are identified and communicated worldwide.

💡Hazard Identification

Hazard Identification is a section within the SDS that lists signal words, warnings, and safety symbols. This section is vital as it alerts users to the potential dangers of a chemical and the necessary precautions. The script highlights its importance in understanding the risks associated with chemical use.

💡First-Aid Measures

First-Aid Measures are outlined in the SDS to provide guidance on the required treatment for a person who has been exposed to a chemical. This is a critical component of safety planning in the lab, ensuring that appropriate responses are known in case of accidental exposure, as discussed in the script.

💡Handling and Storage

Handling and Storage requirements are detailed in the SDS to ensure that chemicals are managed properly to prevent accidents. The script underscores the importance of adhering to these guidelines to maintain a safe laboratory environment.

💡Personal Protective Equipment (PPE)

Personal Protective Equipment, or PPE, is recommended in the SDS to protect individuals from chemical exposure. The script mentions that the SDS describes OSHA's exposure limits and PPE recommendations, highlighting the role of PPE in safety protocols.
