Weekly Field Safety Plan

This Weekly Field Safety Plan is the governing safety document for Cornerstone Electrical Solutions Corp. (C.E.S.) for the week identified at the top of this plan. Every field employee, apprentice, and on-site contractor must read this plan in full at the start of each work week and acknowledge it before beginning work. This plan applies to all residential, commercial, industrial, renovation, new-construction, and service-upgrade electrical work performed by C.E.S. personnel. It covers job-site hazard assessment, personal protective equipment (PPE), lockout/tagout (LOTO), electrical-specific hazards, fall protection, tool and ladder safety, vehicle and driving safety, emergency response, and incident reporting. The plan is reviewed and re-issued every week. Hazards change with each job site — the weekly review is how we confirm that every crew member is aware of this week's conditions.

Before any work begins on a job site each day, the lead electrician or foreman conducts a documented job-site hazard assessment. This assessment identifies: - Electrical hazards (live circuits, energized panels, service drops, hidden wiring). - Physical hazards (heights, confined spaces, wet floors, trip hazards, overhead obstructions). - Environmental hazards (weather, lighting, temperature, nearby equipment). - Other trades working in the same area. Each crew member reviews the assessment and confirms understanding before starting work. If conditions change during the day (new circuit exposed, weather shifts, other trades begin work), the assessment is updated and re-communicated. Weekly: the lead electrician reviews all active job sites for the week, confirms permit and inspection status, and identifies any site that requires special procedures (hot work, elevated work, energized work).

Minimum PPE required on every C.E.S. job site at all times: - ANSI Z89.1 Class E hard hat — in any area with overhead hazards or as required by site. - Safety glasses (ANSI Z87.1) — worn at all times when cutting, drilling, hammering, or working near energized parts. - Electrical hazard (EH) rated safety boots — leather, non-conductive soles. - ARC-rated flame-resistant (FR) clothing — required whenever working on or near energized circuits or equipment that could create an arc-flash hazard. Layering per the incident-energy analysis; minimum CAT 2 (8 cal/cm²) for typical residential/commercial service work, CAT 4 (40 cal/cm²) for service upgrades and panel work on energized 200A+ services. - Insulated rubber gloves with leather protectors — rated for the voltage being worked. Inspect for damage before each use; dielectric test per manufacturer schedule. - Hearing protection — in areas exceeding 85 dB (generators, hammer drills, concrete coring). PPE must be inspected weekly. Damaged PPE is removed from service immediately and reported for replacement. No work proceeds without the correct PPE for the task.

C.E.S. policy is to de-energize before working. Energized work is permitted only when de-energizing introduces a greater hazard or is infeasible (e.g., troubleshooting, life-safety circuits), and only with: - An energized work permit completed and signed by the owner/operations manager. - Proper arc-rated PPE for the calculated incident energy. - An insulated mat or standing surface and rubber gloves. - A second qualified person present as standby. Rules that apply to every job: - Treat every conductor as energized until verified de-energized with a tested voltage tester (test the tester on a known live source before and after). - Lockout/tagout is mandatory before working on de-energized circuits (see Section 5). - Maintain minimum approach distances per NFPA 70E Table 130.4 for the voltage present. - Never work alone on energized equipment. - Use only insulated, rated tools for energized work. - Keep panel covers on when possible; only open the section you are working on. - Do not modify or bypass breakers, grounds, or GFCI protection. Arc-flash boundary: anyone within the arc-flash boundary must wear arc-rated PPE. The boundary and incident energy are determined by the arc-flash analysis or, where absent, by the NFPA 70E tables.

Before any electrical work on de-energized equipment: 1. Notify all affected personnel that LOTO is being applied. 2. Open the disconnect or breaker for the circuit being worked. 3. Apply your personal lock and tag to the disconnect. Each worker applies their own lock — no shared locks, no master keys. 4. Verify de-energization: test the circuit with a verified voltage tester. 5. Release stored energy (capacitors, UPS batteries, motor backfeed). 6. Perform the work. 7. On completion, confirm the area is clear, remove your lock and tag, notify affected personnel, and re-energize. If a worker leaves the site without removing their lock, the lock is removed only by the supervisor following the documented forced-removal procedure. Never bypass or force another worker's lock.

Any work above 6 feet requires fall protection per OSHA 1926 Subpart M: - Personal fall arrest system (harness, lanyard, anchor rated for 5,000 lbs per worker) when on lifts, scaffolds, or unprotected edges. - Ladders used per OSHA 1926 Subpart X — Type IA (300 lb) minimum, inspected before use, set at the correct angle (1:4 ratio), secured top and bottom, three points of contact maintained. Aluminum ladders are prohibited near energized parts — use fiberglass. - Aerial lifts (bucket trucks, scissor lifts) — only trained and authorized operators; fall protection worn and tied off to the lift, never to an adjacent structure. No work on a roof, scaffold, or lift during high winds, lightning, or ice conditions.

Tools are inspected weekly and before each use. Defective tools are tagged out and removed from service. - Power tools: grounded or double-insulated, GFCI protection on all temporary power, cords inspected for damage. - Conduit benders, knockout punches, and cable pullers: used per manufacturer instructions; use proper body mechanics to avoid strain. - Rotary hammers and core drills: use dust extraction for concrete; eye and hearing protection required. - Knives and cutting tools: cut away from the body; retract blades when not in use. - Multi-testers and clamp meters: rated for the category (CAT III/IV) and voltage of the work; verify calibration per the manufacturer schedule. Hot work (soldering, grinding that produces sparks) requires a hot-work permit, fire watch, and a cleared area of combustibles with a charged fire extinguisher within reach.

Company vehicles are operated only by licensed, insured drivers. Seat belts are mandatory. - Pre-trip inspection each day: tires, lights, brakes, load securement. - Secure all tools, conduit, and materials — nothing loose in the cab, ladders and pipe strapped to the rack, weight distributed evenly. - No cell-phone use while driving — hands-free only, and only when safe to pull over for work calls. - Backing: use a spotter or walk around the vehicle first; check for pedestrians, children, and pets. - Lifting: team-lift over 50 lbs; use material carts, hand trucks, and dollies; bend at the knees, keep the load close. Trailers are secured with wheel chocks when disconnected, and the hitch and safety chains are verified before towing.

If an injury, shock, arc flash, or serious incident occurs on a job site: 1. Ensure your own safety first — do not become a second victim. Disconnect power if safe to do so; never touch a person in contact with energized circuits until power is removed. 2. Call 911 immediately for serious injury, shock, unconsciousness, or fire. Give the exact job-site address. 3. Provide first aid/CPR only if trained. Do not move a seriously injured person unless they are in immediate danger. 4. Notify the C.E.S. office immediately at 857-333-4624. 5. Secure the scene for investigation. Do not disturb equipment except to make the scene safe. 6. Complete an Incident Report through the C.E.S. dashboard or technician view the same day. Emergency contacts: - C.E.S. office: 857-333-4624 - Emergency: 911 - Nearest hospital and job-site address must be identified in the daily hazard assessment. Every vehicle carries a first-aid kit and fire extinguisher, inspected monthly.

Every incident, near-miss, and newly identified hazard is reported — no exceptions, no retaliation. Reporting keeps the whole crew safe. - Injuries, property damage, vehicle incidents, equipment failures, and safety violations: file an Incident Report the same day through the dashboard or technician view. - Near-misses (events that could have caused injury or damage but did not): report verbally to the lead electrician and documented in the weekly review below. - New hazards on a job site: reported immediately; work in that area stops until the hazard is controlled. The weekly review on this page is where each crew member confirms they read this plan, reports any incidents or near-misses from the week, and notes corrective actions. The office reviews all submissions and trends them monthly to improve the plan.
