Never kink the hose to stop the flow of concrete. Kinks cause blockages and pressure spikes that can violently and uncontrollably straighten out under pressure. Kinking also damages the reinforcement elements of the hose. Do not attempt to resolve a plugged hose by crushing the sides; this will damage the reinforcing materials and lead to a faster failure. Never hang a two-ended discharge hose from a boom unless you are tying it into a system. Do not use a double-ended hose at the discharge end of a hose system when connected to a boom. Only use hoses with a working pressure rating that meets or exceeds the maximum pressure rating of the concrete pump with which it is being used. Extreme care must be taken before opening any coupling when dealing with a plugged system. Always verify that a blocked hose is not pressurized before opening any coupling. Never use a hose with frays, breaks or exposed braiding/reinforcement on either the inside liner or outside shell.
JOB SITE HOSE SAFETY
Never use compressed air to clean out a hose.
Never drag a hose by attaching to the coupling or drag a hose using a boom arm.
Never beat on a hose with a hammer or other blunt object. The impact risks damaging the built-in reinforcing material, which can lead to premature failure. Always perform internal and external visual inspections before every use, even if this is the second pour of the day.
All items hung from a boom arm should be restrained with safety slings.
Safety slings are the best defense when a hose becomes separated from a boom. It should be lassoed below the hose body on one end and attached to the boom tip on the other. If a separate steel reducer is also used in the tip assembly before the hose, an additional strap must be used to tie the assembly to the boom.
Couplings should never be used as a mounting location for a safety strap.
Slings used on boom tips should be defect-free, meant for that purpose, and inspected frequently.
