Employers are not obligated to provide a designated smoking or vaping area on site. However, failing to do so may lead smokers/vapers within your team to resort to using the footpath outside your premises. This could create a negative impression for clients/customers and is not conducive to the best interests of the business.

The simple answer to your question is: No. Regardless of whether there is a 15kN anchor point or not, where a risk assessment shows that there is no risk of a fall, a harness does not need to be used. Note that this applies to scissor lifts only, not to other MEWP types. The primary means of fall protection on a scissor lift is the handrail around the platform.
