Understanding the "Corrosion" Pictogram and Its Hazards
The Problem
Corrosive chemicals pose serious risks to workers, including severe burns, eye injuries, and damage to equipment and structures. Unfortunately, many incidents occur because workers fail to recognise the hazards or take proper precautions. Today, we’ll focus on the 'Corrosion' pictogram under the Globally Harmonized System (GHS), how to identify corrosive substances, and how to protect ourselves when handling them.
Identify the Hazards
The "Corrosion" pictogram indicates substances that can:
- Cause serious damage to skin and eyes upon contact.
- Corrode metals, potentially leading to leaks, equipment damage, or structural failure.
Examples of Corrosive Substances:
- Acids (e.g., sulphuric acid, hydrochloric acid)
- Alkalis (e.g., sodium hydroxide)
- Bleach, battery acid, and certain industrial cleaners
Hazards on Site:
- Direct contact may result in chemical burns, especially to the skin and eyes.
- Damaged or corroded containers can leak hazardous substances, creating additional safety and environmental risks.
Safety Practices and Preventative Measures
Understand the “Corrosion” Pictogram
- This symbol indicates a substance that is corrosive to skin, eyes, or metals.
- Always read the label for hazard and precautionary statements before use.
Follow Precautionary Instructions
- Wear appropriate personal protective equipment (PPE)—including gloves, goggles, face shields, and chemical-resistant clothing.
- Use respiratory protection if there is a risk of inhaling corrosive vapours or mists.
- Wash hands and exposed skin thoroughly after handling corrosive substances.
Refer to the Safety Data Sheet (SDS)
- SDSs provide detailed information on safe handling, storage, first aid, and emergency response.
- Make sure you understand emergency procedures and proper disposal requirements.
Handle and Store Substances Correctly
- Store corrosive materials away from incompatible substances and metal containers.
- Ensure storage areas are cool, dry, and well-ventilated.
Be Prepared for Emergencies
- Know the locations of eyewash stations and emergency showers.
- Respond to spills or exposures as outlined in the SDS.
Real-Life Case or Scenario
A worker was using an industrial cleaning agent but did not wear gloves. They sustained serious chemical burns to their hands. The container displayed the 'Corrosion' pictogram, but the worker had not noticed it or read the precautionary instructions. This incident could have been prevented by recognising the symbol and using the appropriate personal protective equipment (PPE).
Employee Responsibilities
- Check all chemical labels for the "Corrosion" pictogram and read the instructions carefully.
- Wear the required PPE and follow proper handling procedures at all times.
- Report any damaged containers or unsafe storage practices immediately to your supervisor or safety representative.
Employer Responsibilities
- Ensure all staff are trained in the GHS labelling system and chemical safety procedures.
- Provide appropriate PPE and maintain emergency wash stations (e.g., eyewash and safety showers).
- Ensure corrosive substances are clearly labelled and stored safely according to regulatory requirements.
- Provide up-to-date Safety Data Sheets (SDSs) and ensure they are readily accessible on site.
Discussion & Questions
- “What corrosive substances do we use on site, and what precautions are in place?”
- “Has anyone experienced a near-miss or incident involving corrosive substances?”
Encourage open discussion around safe handling practices and possible improvements.
Commitment/Action Plan
Starting today, let’s commit to identifying the 'Corrosion' pictogram, reading labels and SDSs, and using the correct PPE when handling corrosive substances. Safety starts with knowledge and taking the right precautions.
Wrap-Up
Understanding the 'Corrosion' pictogram is essential to recognising the serious risks posed by corrosive substances. By following CCOHS guidance and your site’s safety procedures, we can help prevent injuries and damage. Thank you for doing your part to keep the worksite safe.
Standards Overview
Under Canadian occupational health and safety regulations, employers must:
- Ensure hazardous substances are properly labelled with appropriate GHS pictograms.
- Provide access to current Safety Data Sheets (SDS) for all hazardous materials on site.
- Train workers on the risks and safe handling procedures for hazardous substances.
- Supply and maintain suitable personal protective equipment (PPE) and emergency equipment such as eyewash stations and spill kits.
