✓ Correct answer: A. They must be clear and easily understoodSafety signs must be immediately clear and comprehensible to all workers so that hazard information is communicated effectively and safety compliance is maintained.
Why the other options are incorrect:
• They can be in any language: Signs must use English or universally recognised symbols; using an arbitrary language may leave workers unable to understand the safety message.
• They are optional if the risk is low: Appropriate signage is required irrespective of how minor a risk may seem; there is no exemption based on low-risk levels.
• They should be decorative: A sign whose purpose is decorative fails to fulfil the legal requirement of communicating safety information.
• They can be handwritten: Handwritten signs are unlikely to meet the standards of clarity and durability required by health and safety regulations.
