Gasman - are there 'RAMS' - no probably not, I have never come across them within council services.
RAMS is shorthand for risk assessment / method statement.a particular construct of the construction industry, and organisations who service or work for this sector, which seems to have infiltrated other areas, - despite no reference to the term RAMS on the HSE website.
However, there will be safe work procedures, derived from the guidance from the WISH - the Waste Industry Safety & Health - forum. This group works closely with the HSE. Search for 'Waste' in HSE site to find all you ever need to know about waste, recycling and collections, plus things you never even thought of, for the curious - as you are.
Waste authorities or companies tend to also develop 'route risk assessment' to supplement any general guidance - WISH 04 on street collections is 46 pages long, although lots of diagrams.
The H&S person will probably guide management to use WISH protocols as much as possible, but is not responsible for controlling all the risks, and may not even be involved in the route risk assessment process as it is primarily operational.
The waste collection function is driven by cost, always has been, and it is not uncommon to see deviations from WISH guidance or in-house procedures. The monitoring of H&S compliance on routes is a key priority for HSE, as this is where theory meets reality and fails.
Having said all that, there are relatively few catastrophic incidents out on the routes, mainly down to the street savvy operatives. Manual handling is less of a risk (nowadays) than you might think, although musculoskeletal injuries are now more subtle than the old back injury. Slips & trips, and being struck by wheelie bins - even falling from the vehicle clamps - are more significant. Also there is a risk to others from these activities, especiallythe reversing of trucks.
