Understanding the "Corrosion" Pictogram and Its Hazards

Hazard Communication

The Problem

Corrosive chemicals pose significant risks to workers, including severe burns, eye damage, and even the corrosion of metal equipment. Despite these dangers, many accidents occur simply because workers fail to recognize the hazards or take the necessary precautions. Today, we will focus on the 'Corrosion' Pictogram introduced by OSHA's Hazard Communication Standard and learn how to identify corrosive hazards and protect ourselves while handling these materials.

Identify the Hazards

The "Corrosion" Pictogram represents chemicals that can:

  1. Cause severe damage to living tissue (skin and eyes).
  2. Corrode metals, potentially leading to container ruptures or leaks.

Examples of Corrosive Chemicals:

  • Acids (e.g., sulfuric acid, hydrochloric acid).
  • Bases (e.g., sodium hydroxide).
  • Industrial cleaners, bleach, and battery acid.

Hazards in the Workplace:

  • Direct contact with corrosive materials can result in chemical burns.
  • Corroded containers can leak hazardous substances, increasing exposure risks.

Safety Practices and Preventative Measures

To mitigate these hazards, always follow these safety practices:

  1. Understand the “Corrosion” Pictogram:

    • Recognize it on chemical labels and associate it with potential harm to skin, eyes, and metals.
    • Always read and follow the hazard statements and precautionary statements on the label.
  2. Follow Precautionary Statements:

    • Wear the required personal protective equipment (PPE), such as gloves, goggles, face shields, and protective clothing.
    • Avoid inhaling dusts or mists by using appropriate respiratory protection.
    • Wash hands and exposed skin thoroughly after handling corrosive materials.
  3. Refer to Safety Data Sheets (SDS):

    • Use the SDS to understand safe handling, storage, and emergency measures for corrosive chemicals.
    • Familiarize yourself with specific guidelines for each material you work with.
  4. Handle and Store Chemicals Safely:

    • Keep corrosive materials away from metal containers to prevent corrosion and leaks.
    • Store chemicals in a dry, cool area as specified by the SDS.
  5. Prepare for Emergencies:

    • Know the location of emergency eye wash and body wash stations.
    • Be prepared to respond to accidental exposure or spills by following SDS recommendations.

Real-Life Case or Scenario

Where possible, use an actual incident that you have experienced or been involved in.

E.g. Here’s an example: A worker handling industrial cleaning agents without wearing gloves suffered severe chemical burns to their hands. They didn’t notice the 'Corrosion' Pictogram on the container or follow the precautionary statements on the label. This injury could have been avoided by recognizing the hazard and wearing the proper PPE.

Employee Responsibilities

  • Always check for the "Corrosion" Pictogram on chemical labels and understand its meaning.
  • Use PPE as outlined in the precautionary statements.
  • Follow all handling and storage instructions provided in the SDS and on product labels.
  • Report any damaged containers or unsafe chemical storage to your supervisor immediately.

Employer Responsibilities

  • Provide training on OSHA’s Hazard Communication Standard and the meaning of pictograms.
  • Ensure all corrosive chemicals are labeled correctly and stored safely.
  • Supply proper PPE and maintain emergency washing stations.
  • Update employees on any new labeling requirements or SDS changes.

Discussion & Questions

  • "What corrosive chemicals are commonly used on this site, and how do we ensure safe handling?"
  • "Does anyone have experience with a corrosive incident? What measures could have prevented it?"

Open the floor for questions about the pictogram or handling corrosive materials safely.

Commitment/Action Plan

Starting today, let’s commit to recognizing the 'Corrosion' Pictogram and taking all necessary precautions when handling corrosive chemicals. Inspect all chemical containers for proper labels and ensure you’re using the correct PPE before starting work.

Wrap-Up

Understanding the 'Corrosion' Pictogram and the associated hazards is critical for maintaining a safe workplace. By following these steps and adhering to OSHA standards, we can protect ourselves and our coworkers. Thank you for your attention and commitment to safety.

Standards Overview

  • The Hazard Communication Standard (HCS) requires chemical labels to include pictograms, like the "Corrosion" Pictogram, to visually communicate hazards.
  • OSHA also mandates the use of Safety Data Sheets (SDS) to provide detailed information about chemical handling, storage, and emergency procedures.
