In reply to Climbing mckay: Yes, and no. Legally PPE is a workplace item and the regulations covering PPE only apply to the workplace (Personal Protective Equipment at Work Regulations (1992))
"What is PPE?
PPE is defined in the Regulations as ‘all equipment (including clothing affording protection against the weather) which is intended to be worn or held by a person at work and which protects him against one or more risks to his health or safety’, eg safety helmets, gloves, eye protection, high-visibility clothing, safety footwear and safety harnesses.
Hearing protection and respiratory protective equipment provided for most work situations are not covered by these Regulations because other regulations apply to them. However, these items need to be compatible with any other PPE provided.
Cycle helmets or crash helmets worn by employees on the roads are not covered by the Regulations. Motorcycle helmets are legally required for motorcyclists under road traffic legislation."
Items used in a non work situation are, absolutely, safety items but are definitely not PPE under the current regulations.
Pedantics aside (my fault, I started it!), PPE, safety equipment or whatever doesn't matter. The OP was missold an item and is entitled to a refund or replacement.
