Professional Line Striping for Contractors

Article 20 of 24

Crew Positioning, Communication, and Personal Protective Equipment

A Professional Crew Works as a Coordinated Unit

Professional line striping places workers near moving vehicles, mobile equipment, pressurized coating systems, wet materials, traffic-control devices, and changing site conditions. Safe production depends on deliberate crew positioning, clear communication, suitable personal protective equipment, and the authority to stop work when conditions become unsafe.

The objective is not to slow production. It is to organize the operation so every worker understands the plan, knows where equipment will move, remains visible to operators and road users, and can respond immediately when conditions change.

Standards Foundation

This article is informed by the current Manual on Uniform Traffic Control Devices, particularly Part 6 on temporary traffic control; OSHA construction requirements for personal protective and lifesaving equipment; OSHA work-zone traffic-safety guidance; and recognized manufacturer instructions for airless striping equipment and coating materials.

The MUTCD establishes traffic-control principles and worker-visibility provisions for applicable temporary traffic-control zones. OSHA requires employers to assess workplace hazards, select suitable protective equipment, train workers, and maintain that equipment in a reliable condition.

State plans, state transportation agencies, municipalities, facility owners, general contractors, and project specifications may establish additional or more restrictive requirements. The employer must identify the standards that apply to each project and incorporate them into the crew’s working plan.

Define Crew Roles Before Work Begins

Every crew member should know who is directing the operation and who is responsible for each critical function. Duties may be combined on a small project, but responsibility should never be left uncertain.

Assignments should be adjusted to the size and complexity of the project. A worker should not be expected to perform two duties simultaneously when one assignment requires uninterrupted attention.

Establish Work Zones Around People and Equipment

The temporary traffic-control plan establishes the larger protected area. Inside that area, the crew also needs working zones around the striping machine, support vehicles, gun assemblies, hoses, containers, stencils, and freshly applied markings.

• Keep workers out of the machine’s forward path and turning radius.
• Do not stand between moving equipment and a fixed object.
• Keep feet, hands, clothing, and tools clear of wheels, drive components, gun mechanisms, and hot surfaces.
• Route hoses so they do not create trip hazards or become caught under wheels.
• Keep materials and tools out of buffer spaces, traffic routes, and escape paths.
• Prevent workers from stepping backward into traffic while concentrating on layout or spray quality.

Never Assume the Operator Can See You

Striping machines, support trucks, trailers, and utility vehicles all have blind areas. Noise, vibration, glare, mirrors, equipment frames, paint containers, and the operator’s attention to the line can reduce awareness of nearby workers.

Before entering an equipment operating zone, make positive contact with the operator and receive acknowledgment. If acknowledgment is lost, stay clear. Visibility is not the same as communication.

Positioning the Machine Operator

The machine operator should have a clear view of the control line, gun position, planned travel path, nearby workers, traffic-control limits, and approaching hazards. The operator should not be required to divide attention between production and duties that belong to a dedicated traffic-control worker.

• Inspect the travel path before moving.
• Use controlled speed appropriate for the site and required line quality.
• Stop when pedestrians or vehicles enter the operating zone.
• Avoid sudden turns or reversals that have not been communicated.
• Shut down and relieve pressure before adjusting or servicing pressurized components.
• Do not leave operating equipment unsecured or accessible to unauthorized persons.

Layout Crew Positioning

Layout work can place personnel outside the immediate protection of the striping machine. Workers may be looking down, pulling tapes or strings, handling chalk lines, or moving backward while concentrating on measurements.

• Complete as much layout as practical inside a controlled closure.
• Assign a lookout when layout personnel cannot continuously monitor traffic.
• Work facing approaching traffic whenever site conditions permit.
• Avoid walking backward without a verified clear path.
• Keep measuring tapes, strings, cords, and chalk lines out of active traffic routes.
• Relocate control points when their original position creates unnecessary exposure.

Backing and Spotter Control

Plan the site and work sequence to eliminate unnecessary backing. When backing is required, the route should be inspected and controlled before movement begins.

1. Confirm that the backing path is clear of people, vehicles, devices, and equipment.
2. Assign one spotter when a spotter is required.
3. Agree on hand signals or radio commands before movement begins.
4. Position the spotter where the driver can see the spotter without placing the spotter in the vehicle path.
5. Prevent other workers from giving competing instructions.
6. Stop immediately if visual or radio contact is lost.

Cameras, mirrors, alarms, and proximity systems are valuable aids, but they do not eliminate the need for a clear path, controlled movement, and an effective spotter when one is required.

Use a Clear Communication System

Communication methods should be simple, understood by the entire crew, and suitable for traffic noise, engines, respirators, hearing protection, darkness, and distance. The crew should not invent signals after movement has started.

One Signal Must Always Mean Stop

Every worker should know the emergency stop signal and have authority to use it. The operator must stop immediately when the signal is given, when communication is lost, or when a person or vehicle enters the operating zone unexpectedly.

Work should not resume until the hazard is controlled, communication is restored, and the responsible person authorizes the restart.

High-Visibility Safety Apparel

Workers exposed to vehicle and equipment traffic must wear the high-visibility safety apparel required by the applicable MUTCD provisions, agency requirements, employer hazard assessment, and site rules. Select the required performance class for the exposure rather than relying on color alone.

• Use apparel labeled as meeting the required performance standard and class.
• Select fluorescent background and retroreflective materials suitable for daytime, nighttime, or low-visibility work.
• Keep vests and garments closed and worn as designed.
• Replace apparel obscured by paint, dirt, fading, damage, or missing reflective material.
• Do not cover high-visibility material with jackets, harnesses, tools, or equipment.
• Consider supplemental high-visibility garments when worker body position or background conditions reduce recognition.

PPE Must Follow the Hazard Assessment

Personal protective equipment is selected after identifying the hazards associated with the site, material, equipment, task, and exposure. It supplements—not replaces—traffic control, ventilation, guarding, safe work practices, equipment maintenance, and other primary controls.

Chemical-Resistant Gloves

Glove selection should be based on the exact coating, solvent, cleaner, and expected contact. A glove described simply as chemical resistant is not necessarily suitable for every product.

• Review the safety data sheet and glove manufacturer’s compatibility information.
• Consider permeation, degradation, breakthrough time, thickness, and task duration.
• Inspect gloves before use and replace contaminated or damaged gloves.
• Remove gloves without transferring contamination to the skin.
• Use separate protection when cut, heat, or abrasion hazards require it.

Respiratory Protection Requires a Program

A respirator should not be selected by appearance, odor, or informal preference. When respiratory protection is required, the employer must follow the applicable respiratory-protection requirements, including hazard evaluation and selection of an approved respirator suitable for the contaminant and exposure.

A required-use program may include medical evaluation, fit testing for tight-fitting respirators, training, inspection, cleaning, storage, cartridge or filter change procedures, and program evaluation.

An organic-vapor cartridge does not automatically protect against paint aerosol, particulates, every solvent, oxygen-deficient conditions, or unknown concentrations. Follow the safety data sheet, exposure assessment, respirator manufacturer’s limitations, and applicable regulations.

Airless Injection Is a Medical Emergency

High-pressure spray can penetrate skin and inject coating, solvent, or other material into tissue. The injury may initially appear small while causing severe internal damage.

• Never place a hand or body part in front of the spray tip.
• Never attempt to stop a leak with a hand, glove, rag, or tape.
• Use the gun trigger lock whenever the gun is not being operated.
• Follow the manufacturer’s pressure-relief procedure before servicing, cleaning, or changing components.
• Obtain immediate emergency medical treatment for a suspected injection injury and identify the injected material.

Hearing Protection and Communication

Hearing protection should be selected from the employer’s noise evaluation and applicable hearing-conservation requirements. Protection must reduce exposure appropriately without creating an unmanaged communication hazard.

If hearing protection makes ordinary speech, warning alarms, or equipment signals difficult to recognize, establish radios, visual signals, specialized communication equipment, or another dependable method before starting work.

Heat, Cold, Sun, and Fatigue

Weather exposure can affect judgment, reaction time, communication, and physical performance. Hot pavement, protective clothing, direct sun, humidity, cold, wind, and long shifts should be considered in the daily plan.

• Provide drinking water, planned breaks, and suitable recovery areas.
• Allow workers to acclimatize as required by the conditions and employer program.
• Recognize the signs of heat illness, cold stress, and fatigue.
• Use sun protection that remains compatible with required PPE.
• Adjust assignments when a worker’s condition could compromise safe performance.

The Pre-Shift Crew Briefing

A short, specific briefing should be conducted before the crew enters the operating area and repeated when the work plan changes.

1. Review the scope, sequence, and expected production movement.
2. Identify traffic routes, equipment routes, blind areas, and restricted zones.
3. Assign the crew leader, operator, spotter, layout, traffic-control, and material duties.
4. Review hand signals, radio channels, call signs, and the emergency stop command.
5. Confirm required PPE and inspect it before use.
6. Identify escape paths, assembly points, first-aid resources, and emergency contacts.
7. Give every crew member an opportunity to identify a hazard or request clarification.

Stop-Work Conditions

The crew should stop and reassess the operation when any of the following occurs:

• A vehicle or pedestrian enters the operating zone unexpectedly.
• Communication between an operator and spotter is lost.
• A worker can no longer remain visible to the operator or traffic.
• Traffic-control devices become displaced or ineffective.
• Required PPE is damaged, contaminated, missing, or unsuitable.
• Equipment develops a leak, damaged hose, failed guard, or unsafe control condition.
• Weather, lighting, visibility, noise, or site activity changes materially.
• A worker reports an uncontrolled hazard, illness, injury, or loss of concentration.
