When working at height, it is crucial to use the appropriate personal protective equipment (PPE) to ensure safety. Here are the key PPE items you should consider:

1. Full Body Harness: A full body harness is essential for fall protection. It should meet standards such as CEN Standard EN 361: 2007 or ANSI/ASSE Standard Z359.1-2007, ensuring it is suitable for preventing falls from height [1].

2. Head Protection: If there is a risk of head injury, wear protective headwear that meets standards like CSA Standard Z94.1-15 or ANSI Standard Z89.1-2003. The helmet should have a retention system with at least three points of attachment and a chin strap [2].

3. Connecting Components: Use connectors such as carabiners that comply with standards like CEN Standard EN 362: 2004 or UIAA Standard 121: 2004. These components are crucial for securing the harness to anchor points [3].

4. Footwear: Ensure you have appropriate footwear that provides good grip and stability to prevent slips and falls.

5. Additional PPE: Depending on the specific hazards of your work environment, you may need additional PPE such as gloves, eye protection, or respiratory protection.

Always conduct a hazard assessment to determine the specific PPE requirements for your work at height and ensure all equipment is inspected before use to confirm it is in good condition. Training on the proper use and limitations of PPE is also essential to ensure safety [4].
