Rosie's answer
Published by SALUSA safe operating procedure for a Hino FM2632 non-destructive digging and vacuum truck should be based on a documented risk assessment, site-specific job safety analysis, utility plans and permits, and the manufacturer’s operating instructions. Before work starts, the employer or supervisor should identify excavation hazards, soil conditions, underground and overhead services, traffic exposure, atmospheric hazards, and the specific risks from vacuum suction and high-pressure air or water. Operators should understand the job site, read and follow the operator’s manual, and use equipment that is appropriately sized and maintained for the task. [1] [3] [9]
Key hazards to identify
- Striking buried electrical, gas, water, sewer, or telecommunications services
- Contact with overhead power lines during truck positioning or boom/hose handling
- Excavation collapse, ground instability, tension cracks, water ingress, and undermining
- Workers or bystanders being struck by moving plant, reversing vehicles, hoses, tools, or flying debris
- Falls while climbing on and off the truck, slips on wet or muddy ground, and falls into open excavations
- Exposure to low oxygen, hazardous gases, vapours, dust, noise, and contaminated spoil
- Injury from high-pressure air or water injection, hose whip, uncontrolled release, or suction entrapment
- Manual handling injuries during hose handling, cover lifting, spoil management, and maintenance tasks
[1] [1] [1] [1] Control measures should follow the hierarchy of controls: eliminate or isolate hazards first, then use engineering controls, administrative controls, and PPE. Establish exclusion zones around the excavation, truck, boom, and hose operating area. Keep spoil, pipes, and materials at least 1 metre back from the excavation edge. Barricade or guard the excavation, provide safe access and egress, manage water accumulation, and stop work if cracks, seepage, undermining, or instability are observed. A competent person should inspect the excavation at the start of each shift and after any event that could affect stability, such as rain, vibration, or adjacent plant movement. [2] [2] [2] [2]
Underground utility location is a critical control. Before excavation, obtain current utility information, contact utility owners, and have services positively identified and marked. When approaching the estimated utility location, use safe and acceptable exposure methods such as careful hand digging or vacuum excavation/potholing to visually confirm the exact location and depth. Do not assume the utility runs straight or at constant depth between potholes. De-energize or isolate services where necessary, maintain emergency contact numbers, and use non-conductive tools where appropriate. [1] [1] [6] [6] [10]
For suction and high-pressure air or water hazards, never direct air or water at people, never use the lance or wand blindly near known or suspected utilities, and keep hands, feet, and body parts clear of the nozzle and suction end. Use the lowest effective pressure, maintain hose integrity, secure couplings, and control hose movement to prevent whip. Establish a no-go zone around the suction hose and excavation edge, and ensure communication between operator and spotter is clear before starting. Stop immediately if unexpected resistance, arcing, gas odour, damaged coating, or exposed utility is encountered. Treat all exposed services as live until confirmed otherwise. [3] [3] [6]
Operator competency and supervision
- Operators must be trained, authorised, and competent in the specific vacuum excavation truck, its controls, shutdown systems, and manufacturer limits
- Competency should cover excavation hazards, utility locating, potholing techniques, traffic management, emergency response, hose and pressure hazards, and daily inspections
- A competent person should supervise excavation safety and inspect the work area and excavation regularly
- Use a spotter where visibility is restricted, when working near overhead lines, utilities, pedestrians, or traffic
- Workers entering excavations or pits should also be trained in excavation hazards, access/egress, atmospheric hazards, and rescue arrangements
[2] [3] [3] [7] Pre-start inspection
- Confirm the risk assessment, permits, utility plans, dial-before-you-dig information, and site briefing are complete
- Inspect the truck, brakes, steering, lights, reversing alarm, tyres, mirrors, cameras, and warning devices
- Check PTO, vacuum system, water or air system, pressure gauges, relief devices, hoses, couplings, boom, nozzle, lance, tank, locks, and emergency stop functions
- Verify all guards, warning labels, ladders, access steps, and handholds are in good condition
- Ensure fire extinguisher, first aid kit, communication devices, spill kit, and rescue equipment are available
- Remove defective equipment from service and ensure scheduled maintenance and inspections are current
[3] [3] [3] [3] Excavation safety controls should include confirming soil conditions, selecting protective measures appropriate to depth and ground conditions, keeping people out of unsupported excavations where collapse is possible, and providing safe entry and exit. Ladders should be secured and located so workers do not have to travel excessive distance to escape. If the excavation could contain hazardous atmospheres, test the air before entry and monitor as needed. If the excavation meets the definition of a confined space, apply the confined space entry program, including isolation, atmospheric monitoring, communication, attendant arrangements, and rescue planning. [1] [2] [2] [2] [12]
Traffic management is required whenever the truck operates on or near roads, mobile plant routes, or public areas. Prepare a traffic management plan that addresses vehicle approach, parking, reversing, pedestrian separation, cones, barriers, signage, lighting, and spotters or traffic controllers where needed. Position the truck to minimise reversing and avoid setting up where workers are exposed between the truck and excavation. All personnel exposed to traffic should wear high-visibility clothing. [2] [2] [5]
PPE
- Hard hat
- Safety glasses, with face shield where splash or flying debris risk exists
- Gloves suitable for abrasion, cuts, wet work, and utility exposure
- Safety boots with protective toe and slip-resistant sole
- High-visibility clothing
- Hearing protection where noise levels are elevated
- Respiratory protection if dust, vapours, aerosols, or contaminated atmospheres cannot be otherwise controlled
- Protective clothing appropriate to mud, contaminated spoil, weather, and high-pressure water exposure
[3] [9] [4] Emergency procedures should cover utility strike, gas release, electric contact, trench collapse, engulfment, hose failure, pressure injection injury, fire, vehicle incident, medical emergency, and environmental spill. Stop work, isolate the area, shut down equipment if safe to do so, and contact emergency services and the relevant utility owner immediately. Do not attempt rescue from an unstable excavation without proper controls and trained rescue capability. Keep first aid equipment on site, maintain reliable communications, and ensure all workers know emergency contacts and escalation steps. Any suspected high-pressure injection injury requires urgent hospital treatment even if the wound appears minor. [1] [2] [2] [12]
Maintenance requirements should include planned preventive maintenance, daily operator checks, defect reporting, lockout or isolation before repair, and servicing only by qualified personnel. Hoses, couplings, pressure systems, vacuum components, tank closures, ladders, guards, and emergency devices should be inspected regularly and replaced when worn or damaged. Keep maintenance records, inspection checklists, and evidence that warning labels remain legible and safety-critical systems are functional. [3] [3] [4] [4]
For WHS/OHS compliance, the employer should ensure the work is planned, risk assessed, supervised, and carried out by competent persons; utilities are located by safe and acceptable means; excavations are inspected by a competent person; safe access, barriers, and traffic controls are provided; atmospheric hazards and confined space risks are managed; PPE is selected through hazard assessment; and training, inspections, maintenance, and emergency arrangements are documented. In an Australian WHS/OHS context, this procedure should be aligned with the applicable state or territory WHS/OHS Act and Regulations, excavation work requirements, plant regulations, high risk construction work obligations where applicable, utility owner rules, and relevant codes of practice for excavation work, managing risks of plant, confined spaces, hazardous manual tasks, PPE, and traffic management.

# PROGRAM DIRECTIVE (cont.) ## Citation Guidance associated with Step C, 29 CFR 1926.651(b)(3) - Compliance with determining the exact locations of underground installations by safe and acceptable means. (cont.) including the depth, of underground utility installations can be determined by "potholing". Potholing is an investigating method used to carefully excavate small vertical test holes from the surface to a buried utility line to expose and visually verify the specific location and depth. Oregon OSHA regulations do not dictate how frequently or far apart an employer must pothole; It is performance based. There have been many examples of utility installation damages that have occurred as the result of the employer attempting to excavate the portion of utility between two potholes with a powered track hoe excavator that were fifty feet apart. In these examples of damages, a common cause was that the excavator assumed the utility was horizontally level and without fluctuation in depth or containing any irregularities such as capped off "T" fittings from previous service lines that had been disconnected. The excavator operator, working off those assumptions, scrapped soil away at a rate of a few inches pure bucket cycle, snagging the capped off “T” rising above the utility, resulting in damage and a release of natural gas. Safe and acceptable means used when the excavation approaches the estimated utility location or while potholing to determine the exact location of underground installations include the following methods: a) Hand digging. This method of potholing utilizes hand tools that are used with appropriate investigative caution. Tools, such as shovels and trowels, are typically used to manually uncover and remove material at a cautionary exploratory rate of an inch or two at a time. Constant attention and care need to be taken to prevent damage to utilities during the exploratory potholing process. Non- conductive hand tools and insulated probes are per…

# BEST PRACTICES FOR VACUUM LIFT SYSTEMS (cont.) ## Pre Operation: (cont.) • A discussion between supervisory personnel and operators takes place to allow for pre-planning of the work to be done, including operation of the vacuum lifting system. All personnel should have a thorough understanding of the job site. • The equipment available for use at the jobsite is appropriately sized and rated for the job. - A job safety analysis (JSA) is conducted to determine individual job responsibilities and all related safety concerns. Potential hazards must be identified and addressed. • Operators read and understand the operator's manual prior to equipment use. Keep the operator's manual with the equipment at all times so it is available to the personnel operating the vacuum- lifting system. • Locate all overhead lines, and maintain the designated minimum clearance distance found in OSHA'S regulations at 29 CFR 1926.1408. Always use a spotter. - All maintenance and inspections, as indicated in the operator's manual have been performed and are up to date. Only qualified individuals are authorized to service the equipment, including pad replacement. • Remove damaged or defective equipment from service. • Have a portable fire extinguisher that is fully charged and available for use Make sure all designated personnel are trained on its proper use. • Operators and ground personnel establish the designated method of communication before starting work. • Personnel are supplied and trained on the appropriate personal protective equipment (PPE) as required for the task, such as hard hats, safety glasses, reflective vest, safety-toed shoes, gloves, hearing protection and protective clothing. - Make sure all warning labels are legible. If any are missing or illegible, replace them prior to the operation of the equipment.

# What types of PPE may be necessary? Your hazard assessment should determine if your employees need any of the following types of PPE: - Eye and face protection ◆ Fall protection - Foot protection • Hand/general skin protection - Head protection • Hearing protection • Leg protection ● Personal floatation device • Respiratory protection • Torso/general body protection ## How to do a PPE hazard assessment ## Do a baseline survey to identify workplace hazards A baseline survey is a thorough evaluation of your entire workplace - including work processes, tasks, and equipment - that identifies safety and health hazards. A complete survey will tell you what the hazards are, where they are, and how severe a potential injury could be. ## Suggestions: Use safety data sheets (SDS) to identify chemical hazards. A safety data sheet has detailed information about a hazardous chemical's health effects, its physical and chemical characteristics, and safe handling practices. Review equipment owner and operator manuals to determine the manufacturer's safety warnings and recommended PPE. Conduct a job-hazard analysis (JHA) - a method of identifying, assessing, and controlling hazards associated with specific jobs. A JHA breaks down a job into tasks. You evaluate each task to determine if there is a safer way to do it. A job-hazard analysis works well for jobs with difficult-to-control hazards and jobs with histories of accidents or near misses. JHAS for complex jobs can take a considerable amount of time and expertise to develop. You may want to have a safety professional help you. Have an experienced safety professional survey your workplace with you. 4

# Trenching and Excavation (cont.) ## What are the hazards associated with trenching and excavation? (cont.) - Contact with buried service lines such as electrical, natural gas, water, sewage, telecommunications, etc. - Contact with overhead electrical lines. - Slips, trips and falls as workers climb on and off equipment, or from inappropriate access and egress methods. - Being struck by moving machinery, or by falling or flying objects. - Hazards related to materials handling (e.g., lifting, struck by, crushed between, etc.). ## What is meant by soil types? Definitions of soil types vary by jurisdiction in Canada. In addition, some jurisdictions have not defined soil types, but do require preventative measures when an excavation reaches a certain depth or proportion. When a soil type is defined, the purpose is to try to identify or predict the potential for the soil to move and cause a collapse while the work is being done. Soil types typically use a scale of 1 to 4 where 1 is hard and dense to 4 which is loose, soft, wet or muddy soil, or a scale of A to C where A is hard and solid, and C is soft, sandy, filled or loose. The soil type is determined by the characteristics of the soil's consistency, ease of removal, appearance, ability to excavate with hand tools vs. machine, water seepage, whether the soil has been excavated before, etc. ## What should occur before beginning an excavation? The employer or supervisor is responsible for the work, and must take the necessary steps to identify all the hazards and risks before beginning any work. These steps include to: - Identify the soil type(s) related to the excavation or trench you are going to dig. Soil properties often vary widely within a single trench (e.g., the soil type changes from top to bottom and along the length of a trench). - Look for the legislative requirements that apply in your jurisdiction and the type of protective measures to be taken. - Locate all buried services.
