Safe Handling and Storage of Chemicals in the Workplace: Expert Tips
Chemicals are a vital part of many industries, but their mishandling can lead to severe health risks, environmental damage, and costly accidents. Implementing robust safety measures is crucial for protecting your workforce and ensuring compliance with Australian regulations. This article provides expert tips and best practices for the safe handling and storage of chemicals in the workplace.
1. Understanding Safety Data Sheets (SDS)
A Safety Data Sheet (SDS), previously known as a Material Safety Data Sheet (MSDS), is a comprehensive document that provides crucial information about a chemical substance. It's the cornerstone of any chemical safety programme. Every chemical used in the workplace must have an accessible SDS.
Key Information in an SDS
Identification: Includes the chemical name, synonyms, and manufacturer details.
Hazard Identification: Details the potential hazards associated with the chemical, such as flammability, toxicity, and corrosivity.
Composition/Information on Ingredients: Lists the ingredients of the chemical and their concentrations.
First-Aid Measures: Provides instructions on what to do in case of exposure, including inhalation, ingestion, skin contact, and eye contact.
Fire-Fighting Measures: Outlines appropriate fire extinguishing techniques and equipment.
Accidental Release Measures: Details procedures for containing and cleaning up spills or leaks.
Handling and Storage: Provides guidance on safe handling practices and storage requirements.
Exposure Controls/Personal Protection: Specifies recommended exposure limits and personal protective equipment (PPE) such as gloves, respirators, and eye protection.
Physical and Chemical Properties: Describes the chemical's physical state, odour, pH, boiling point, etc.
Stability and Reactivity: Indicates the chemical's stability and potential reactivity with other substances.
Toxicological Information: Provides information on the chemical's potential health effects.
Ecological Information: Details the chemical's impact on the environment.
Disposal Considerations: Outlines proper disposal methods.
Transport Information: Specifies transportation requirements.
Regulatory Information: Lists relevant regulations and standards.
Other Information: Includes any other relevant information.
Actionable Tip: Ensure all employees have easy access to SDSs for every chemical they work with. This can be achieved through physical binders, electronic databases, or a combination of both. Regularly review and update SDSs to reflect the most current information. You can learn more about Osh and how we can help you manage your chemical safety documentation.
Common Mistake to Avoid: Failing to read and understand the SDS before handling a chemical. This is a critical oversight that can lead to accidents and injuries.
2. Proper Labelling and Storage
Correct labelling and storage are essential for preventing accidents and maintaining the integrity of chemicals. Clear and accurate labels provide immediate information about the contents of a container, while proper storage prevents leaks, spills, and dangerous reactions.
Labelling Requirements
Chemical Identity: The label must clearly identify the chemical name.
Hazard Warnings: Labels should include appropriate hazard symbols and warnings, such as "Flammable," "Corrosive," or "Toxic."
Manufacturer Information: Include the name and contact information of the manufacturer or supplier.
Date of Receipt/Opening: This helps track the age of the chemical and ensure it's used within its shelf life.
Storage Best Practices
Segregation: Store incompatible chemicals separately to prevent dangerous reactions. For example, acids should be stored away from bases, and oxidisers should be stored away from flammable materials.
Ventilation: Store chemicals in well-ventilated areas to prevent the build-up of hazardous vapours.
Temperature Control: Maintain appropriate storage temperatures as specified in the SDS. Some chemicals require refrigeration or controlled heating.
Security: Restrict access to chemical storage areas to authorised personnel only.
Containers: Use appropriate containers that are compatible with the chemical being stored. Ensure containers are tightly sealed to prevent leaks and spills.
Shelving: Use sturdy shelving that can support the weight of the containers. Avoid storing chemicals on the floor.
Spill Containment: Provide spill containment measures, such as drip trays or absorbent materials, to contain any leaks or spills.
Actionable Tip: Implement a colour-coded labelling system to quickly identify different hazard categories. Regularly inspect storage areas for leaks, spills, and damaged containers. Consider our services for a comprehensive chemical storage audit.
Common Mistake to Avoid: Storing chemicals alphabetically without considering their compatibility. This can lead to dangerous reactions if incompatible chemicals are stored next to each other.
3. Handling Procedures and Spill Control
Safe handling procedures minimise the risk of exposure and accidents. Effective spill control measures prevent environmental contamination and protect worker health.
Safe Handling Practices
Personal Protective Equipment (PPE): Always wear appropriate PPE, such as gloves, eye protection, and respirators, when handling chemicals. The SDS will specify the required PPE.
Minimise Exposure: Avoid direct contact with chemicals. Use tools and equipment to handle chemicals whenever possible.
Proper Ventilation: Work in well-ventilated areas or use local exhaust ventilation to minimise inhalation of hazardous vapours.
Hygiene: Wash hands thoroughly after handling chemicals and before eating, drinking, or smoking.
Training: Ensure all employees are properly trained in safe handling procedures.
Spill Control Measures
Spill Kit: Maintain a well-stocked spill kit in areas where chemicals are handled or stored. The kit should include absorbent materials, neutralising agents, PPE, and disposal bags.
Spill Response Plan: Develop a written spill response plan that outlines the steps to be taken in the event of a spill. Ensure all employees are familiar with the plan.
Containment: Immediately contain the spill to prevent it from spreading. Use absorbent materials or barriers to create a dam around the spill.
Clean-Up: Clean up the spill using appropriate methods and materials. Follow the instructions in the SDS.
Disposal: Dispose of contaminated materials in accordance with local regulations.
Reporting: Report all spills to the appropriate authorities.
Actionable Tip: Conduct regular drills to practice spill response procedures. This will help employees react quickly and effectively in the event of a real spill. Refer to frequently asked questions for more information on chemical handling regulations.
Common Mistake to Avoid: Using incorrect absorbent materials for specific chemicals. This can lead to dangerous reactions or ineffective clean-up.
4. Ventilation and Exposure Control
Adequate ventilation is crucial for controlling airborne concentrations of hazardous chemicals. Exposure control measures protect workers from inhaling or absorbing harmful substances.
Types of Ventilation
General Ventilation: Provides a general flow of air throughout the workplace to dilute airborne contaminants.
Local Exhaust Ventilation (LEV): Captures contaminants at their source before they can disperse into the workplace. Examples include fume hoods, dust collectors, and welding exhausts.
Exposure Limits
Exposure Standards: Australian regulations set exposure standards for many hazardous chemicals. These standards specify the maximum allowable airborne concentration of a chemical over a specified period.
Monitoring: Regularly monitor airborne concentrations of hazardous chemicals to ensure they are below the exposure standards.
Exposure Control Measures
Engineering Controls: Implement engineering controls, such as ventilation systems and enclosed processes, to minimise exposure.
Administrative Controls: Implement administrative controls, such as work practices and training programmes, to reduce exposure.
Personal Protective Equipment (PPE): Provide and require the use of appropriate PPE when engineering and administrative controls are not sufficient to control exposure.
Actionable Tip: Conduct regular air monitoring to assess the effectiveness of ventilation systems and exposure control measures. Ensure that ventilation systems are properly maintained and inspected. Consider a professional assessment to ensure your systems are adequate.
Common Mistake to Avoid: Relying solely on PPE without implementing engineering or administrative controls. PPE should be used as a last resort, not the primary means of controlling exposure.
5. Emergency Procedures
Having well-defined emergency procedures is essential for responding effectively to chemical-related incidents. This includes procedures for fires, explosions, spills, and medical emergencies.
Emergency Response Plan
Emergency Contact Information: Include a list of emergency contact numbers, including fire department, ambulance, and poison control centre.
Evacuation Procedures: Outline clear evacuation procedures, including designated evacuation routes and assembly points.
First Aid: Provide first aid training to employees and ensure that first aid kits are readily available.
