- Poor housing conditions in Plymouth's private rental sector cost the NHS over 贈10 million annually, with around 118 deaths attributed to poor housing each year. - The Housing Health and Safety Rating System (HHSRS) is used to assess 29 types of potential hazards in homes and assign a risk score based on the likelihood and potential outcome of harm. - For the hazard of falls on stairs, factors like uneven steps, lack of handrails, poor lighting, and hard surfaces increase the likelihood and severity of injury from falls, resulting in an HHSRS score over the threshold for a Category 1 hazard requiring remedial action.
