Section 1926.97 Electrical Protective Equipment Checklist

By QuickBidSetup Editorial Team · Published October 28, 2026 · Sources linked below

Trade contractors and commercial estimators regularly encounter scopes where crews work near energized lines or temporary power distribution. Under OSHA Section 1926.97, employers must provide, maintain, and inspect specialized electrical protective equipment, including rubber insulating gloves, blankets, matting, sleeves, line hose, and covers. Ensuring compliance requires estimators to price gear purchases, scheduled electrical proof tests, and daily visual checks directly into project estimates and project timelines. This checklist-driven guide outlines standard requirements and bidding practices to keep field crews compliant and bids accurate.

Procurement Checklist: Design, Marking, and Voltage Ratings

Electrical protective gear must satisfy strict manufacturing and certification benchmarks before arriving on a jobsite. Blankets, gloves, and sleeves must be produced by a seamless process. Equipment markings must be nonconducting and applied so they do not impair insulating properties, with glove markings confined strictly to the cuff area. Estimators reviewing equipment submittals should check items against key classification criteria:

• Voltage Classes: Equipment is classified as Class 00, Class 0, Class 1, Class 2, Class 3, or Class 4.
• Ozone Resistance: Nonozone-resistant rubber is designated Type I, whereas ozone-resistant material is marked Type II. Visible cracking, checking, breaks, or pitting during an ozone test indicates material failure under Section 1926.97.
• Proof Testing Durations: AC or DC proof tests verify that equipment can withstand the voltages involved. The test voltage must be applied continuously for 3 minutes for items like blankets, gloves, and sleeves, while matting requires continuous application for 1 minute.
• Soak and Current Criteria: Insulating gloves must withstand AC proof testing following a 16-hour water soak. For 60-hertz AC tests, current following the 16-hour soak cannot exceed Table E-1 thresholds by more than 2 milliamperes.
• Other Protective Gear: Non-rubber plastic guard equipment must withstand system voltages without breakdown, keeping equipment current below 1 microampere per kilovolt of phase-to-phase voltage for primary worker insulation.

Daily Field Inspection and Out-of-Service Criteria

Field supervisors and tradespeople must inspect rubber gear before each day starts and immediately after any incident that might cause physical harm. Insulating gloves require an air test combined with a visual check. Under Section 1926.97, employers must immediately pull gear from service if it displays any of the following flaws:

• Holes, tears, punctures, or cuts
• Embedded foreign objects
• Ozone checking or ozone cutting characterized by interlacing cracks
• Changes in material texture, including swelling, softening, hardening, or becoming sticky or inelastic
• Any physical defect that damages the insulating properties

Surface irregularities from manufacturing molds, such as indentations or protuberances, are acceptable only if they blend into a smooth slope when stretched, or if foreign material remains embedded and stretches when folded. Equipment with unresolved defects must be removed from the field for certified testing.

Protector Glove Requirements and Hand Dexterity Exceptions

To safeguard rubber from punctures and abrasions, protector gloves must be worn over insulating gloves. However, eCFR § 1926.97 establishes specific limited-use exceptions when workers handle small parts requiring unusual finger dexterity:

• Class 00 gloves can be used without protector gloves under limited-use conditions if circuit voltage does not exceed 250 volts AC or 375 volts DC.
• Class 0 gloves may be used without protector gloves under limited-use conditions requiring high finger dexterity.
• Other equipment classes may be used without protector gloves only if the employer proves the risk of physical damage is small and issues gear rated one class higher than required for the voltage involved.
• Retest Mandate: Any insulating glove used without an outer protector glove cannot be reissued or reused until it passes laboratory electrical retesting.

Estimating Storage, Maintenance, Salvage, and Retest Costs

Estimators must price ongoing equipment care into bids rather than treating protective gear as a one-time purchase. Incorporating compliance expenses into general conditions estimating prevents profit erosion across long project schedules:

• Controlled Storage: Insulating goods must be stored away from light, temperature extremes, excessive humidity, ozone, and chemical contaminants. Bidders should budget dedicated protective storage bags and boxes.
• Periodic Proof Testing: Table E-4 and Table E-5 mandate regular electrical retesting intervals. Estimators should carry line items for certified laboratory testing services and shipping.
• Salvage Allowances: Damaged items do not always require total disposal. Defective rubber insulating line hose can be cut shorter to remove damaged sections. Class 1, Class 2, Class 3, and Class 4 rubber insulating blankets may be salvaged by trimming out damaged areas, provided the remaining undamaged blanket measures at least 560 millimeters by 560 millimeters (22 inches by 22 inches). Minor physical punctures or tears on gloves and sleeves may also be repaired using compatible patches or compatible liquid repair compounds.

Schedule Allowances and Bid-Day Verification

Electrical safety requirements affect project milestone pacing. Laboratory testing turnarounds can remove personal protective equipment from service for multiple days, creating downtime unless backup inventory is available on site. Project managers and estimators must account for compliance during schedule development and bid preparation:

• Rotation Buffers: Bid enough redundant Class 00 through Class 4 inventory so crews maintain productivity while primary gear completes required retesting cycles.
• Shift Preparation Time: Include time for daily visual checks and glove air tests before energized tasks commence.
• Bid Verification: When finalizing numbers, use your bid day checklist to ensure recurring testing charges, storage containers, and replacement allowances are included in labor burden or jobsite overhead.
