SF-10A-04 Type II Class E Industrial Safety Helmet

Product Type: Non-Vented Electrical Hard Hat with 4-Point Ratchet Suspension

Designed for electrical utilities and demanding industrial sites, the SF-10A-04 combines an impact-absorbing foam liner, 4-point ratchet suspension and chin strap to manage crown and lateral impacts while maintaining a secure fit. The non-vented tested configuration met ANSI/ISEA Z89.1-2014 (R2019) Type II Class E performance requirements in ICS report T19946-03-1, including a 20,000 V electrical insulation test.

Overview

The internal energy-management liner helps absorb impact forces from the crown, front, rear and sides. It works together with the suspension system to distribute loads and maintain protective clearance between the shell and the wearer’s head.

The rear ratchet provides quick fit adjustment, while the chin strap improves helmet retention during movement. A comfort pad supports stable, long-duration wear without replacing the protective function of the underlying impact liner.

01 Multi-Directional Impact Management

The impact-absorbing liner deforms under load to help reduce energy transferred from crown and off-center impacts. The tested Type II configuration includes impact attenuation and penetration tests at multiple positions.

02 Tested Electrical Configuration

The non-vented Class E configuration completed a 20,000 V insulation test and a 30,000 V no-burn-through check. Shell openings or unauthorized structural modifications may invalidate this tested performance.

03 Dual-Layer Protection and Retention

The foam liner manages impact energy, while the 4-point suspension distributes pressure and maintains clearance. The ratchet headband and chin strap help keep the helmet correctly positioned during active work.

04 Controlled OEM Customization

Colors, logos, reflective elements and compatible accessories can be reviewed for project orders. Paints, solvents, adhesives, metal components or shell modifications must be approved before production to avoid affecting impact or electrical performance.

Application

Recommended for electrical utility inspection, industrial maintenance and worksites with foreseeable crown or lateral impact hazards. PPE selection must follow the employer’s hazard assessment. Class E testing does not authorize intentional contact with energized conductors or replace insulated gloves, tools and safe-work procedures.

FREQUENTLY ASKED QUSTIONS

Standards, Electrical Protection & Customization

Is the SF-10A-04 ANSI certified?

No. ICS report T19946-03-1 is a laboratory test report showing that the assessed configuration met relevant ANSI/ISEA Z89.1-2014 (R2019) Type II Class E performance requirements. It should be described as “tested to,” not “ANSI certified.”

What protection does ANSI Type II provide?

Type II covers crown and lateral impact hazards. The report includes top-impact tests, multi-direction impact attenuation and off-center penetration testing.

What does Class E mean?

Class E identifies electrical insulation performance. The tested configuration completed a 20,000 V test for three minutes and a 30,000 V no-burn-through check.

Can ventilation holes be added?

Ventilation holes should not be added to the Class E configuration. Openings or structural changes may reduce electrical insulation and invalidate the tested configuration.

Can workers use it for direct contact with live conductors?

No. Class E performance does not make the helmet safe for intentional contact with energized conductors. Workers must still follow approved electrical safety procedures and use the required insulated PPE and tools.

What configuration was tested?

The assessed samples used a blue, non-vented shell, a 4-point ratchet suspension and a chin strap with chin cup.

Can the color, logo or accessories be customized?

Customization can be reviewed for OEM and project orders. Colors, coatings, reflective films, headlamps, goggles and earmuffs must be confirmed against the ordered configuration and their applicable test evidence.

What does the impact-absorbing liner do?

The liner helps absorb and distribute energy from crown and lateral impacts. It works together with the suspension system rather than replacing it.

Should the helmet be replaced after an impact?

Remove the helmet from service after a significant impact, even if external damage is not obvious. Replace it according to the manufacturer’s inspection and replacement instructions.

Can the foam liner be cut or modified?

No. Cutting, drilling, sanding or removing sections of the liner may reduce impact protection and invalidate the tested configuration.

Can paint, glue or solvents be applied to the helmet?

Use only manufacturer-approved products. Unapproved paints, solvents and adhesives may damage the shell or liner and affect impact or electrical performance.
