Check each coverall for the specific certifications that it has achieved.

pH7 partners with globally recognised manufacturers to ensure consistent compliance across our hazchem PPE range. Every coverall we supply is traceable to its certification and documentation, supporting your site’s HSWA and WorkSafe NZ compliance obligations. This gives you confidence that your protective garments are fit-for-purpose, regulation-ready, and trusted in high-risk environments.

Yes, our hazchem coveralls are designed to be worn over standard workwear or uniforms as an additional protective barrier layer. Their generous fit and ergonomic design allow unrestricted movement while maintaining a full-body seal against hazardous liquids, particulates, and biological contaminants.

Some coveralls such as the SureShield SS150 and SS200 and the AlphaTec 1500 and 2000 do allow warm air to permeate through the material and can be more comfortable to wear for longer duration and in hot environments. 

However, chemical suits such as the AlphaTec 2300 Plus, 3000, 4000 and 5000 are not breathable by design. It’s important that you choose the correct coverall for your application. Breathable suits are rarely appropriate when working with toxic or corrosive chemicals.  Our pH7 staff can help you choose the correct coverall for your application.

Selecting the correct coverall begins with a hazard assessment of the substances and tasks involved. Different chemicals and exposure levels require different protection types and fabric technologies. pH7’s hazchem coveralls are available in Type 1, 3, 4, 5, and 6 classifications, each designed for specific levels of liquid or particulate protection:

1. Type 1 – Gas tight chemical protective clothing
2. Type 3 – Liquid-tight chemical protective clothing (pressurised liquid spray or jet).
3. Type 4 – Spray-tight protective clothing (non-pressurised liquid spray).
4. Type 5 – Particle-tight protective clothing (solid hazardous dusts such as asbestos).
5. Type 6 – Limited splash protection (low-level liquid exposure).

When choosing a coverall, consider:

• The chemical’s physical form (liquid, mist, vapour, or solid).
• The duration and frequency of exposure.
• The work environment (temperature, ventilation, and required mobility).
• The need for antistatic or biological protection, which may require additional EN 1149 or EN 14126 compliance.

pH7 partners with leading PPE manufacturers and uses data from tools such as the Ansell Guardian chemical permeation database to help you match garments to specific substances and exposure levels. Our team can provide guidance and certification documentation to ensure your coverall selection aligns with WorkSafe NZ and HSWA requirements, giving you confidence that your PPE is fit-for-purpose and fully compliant.

Our protective coveralls are constructed from high-performance barrier fabrics engineered to deliver reliable protection while maintaining wearer comfort and mobility. Our range includes garments made from microporous film laminate, SMS (Spunbond-Meltblown-Spunbond) non-woven polypropylene, and other multi-layer composite materials designed for specific hazard environments.

• Microporous film laminate – Provides an effective barrier against liquid splashes and fine particulates, while allowing water vapour permeability for improved breathability during long shifts.
• SMS fabric – Combines mechanical strength, tear resistance, and breathability, making it ideal for dusty or low-level chemical environments.
• PE-coated and reinforced options – Used in Type 3 and 4 coveralls where spray-tight or liquid-tight protection is required.
• Multi-layer chemical barrier material – Proprietary fabrics designed for protection against a wide range of chemical liquids and hazardous particulates.
• Multi-layer rubber and chemical barrier layers – Proprietary fabrics used in the construction of gas tight and liquid tight coveralls for the harshest environments and emergency response teams.

All materials are tested and certified to recognised European standards so you have the confidence that they will perform in your environment.

Yes, pH7 offers a range of chemical protective coveralls specifically designed for handling hazardous substances.  However, not all coveralls protect against all chemicals, so it’s important that choose the correct coverall for your application.  Asking pH7 to conduct an Ansell Chemical Guardian Assessment is a good place to start.  This will help identify the correct barrier material you should be using for the hazardous chemicals you need to be protected from. 

All chemical protective coveralls supplied by pH7 are independently tested and certified, ensuring compliance with the relevant European standards. Whether you’re handling industrial solvents, acids, cleaning agents, or biological contaminants, our garments form a reliable barrier that safeguards workers and supports regulatory compliance.

This depends on the coverall type, material, and intended use. Coveralls typically fall into three categories:

1. Disposable coveralls – designed for single use and should be disposed of after each shift. These include all coveralls in the SureShield range and the AlphaTec 1500, 2000, and 2300 Plus styles.
2. Limited Life Coveralls – these are coveralls that can be reused several times abut are cannot be laundered. This includes styles such as the AlphaTec 3000, 4000, and 5000.  These coveralls can be re-worn until they become damaged, chemically contaminated or need changing due to hygiene reasons (i.e. they get smelly).  Rinsing these chemical suits after use with clean water and allowing them to air dry will mean they can be re-used for some time.
3. Reusable Coveralls – these are coveralls typically constructed from heavy duty fabrics including PVC or multi-layer rubber and chemical barrier films. They can be decontaminated after each use, and some can be reused for up to 10 years.  However, it’s important that users fully understand the maintenance requirements for such coveralls.

Selecting the correct size is essential to ensure both comfort and full protective performance. A properly fitted coverall should allow free movement without restricting mobility or causing fabric tension at stress points such as the shoulders, knees, and crotch.

Our coveralls are designed to be worn over standard workwear, so we recommend selecting a size that provides adequate room for layering and range of motion. Many garments feature elasticated cuffs, ankles, hoods, and waists, as well as gusseted panels and ergonomic seam placement to enhance flexibility and maintain a secure barrier when bending or stretching.

Each product includes a detailed size chart based on body height, chest, and waist measurements.

If you’re between sizes, choose the larger option to prevent strain on seams and zippers, particularly for chemical-resistant and Type 3/4 certified coveralls, where barrier integrity is critical.

Our technical team can assist with fit and garment selection to ensure each worker achieves optimal protection.

Yes, our protective coveralls are designed to safeguard against a wide range of particulate, liquid, and aerosol hazards. Most garments in our range are Type 1, 3, 4, 5, or 6 certified under EN 14605, EN 13982-1, and EN 13034, providing graduated levels of protection depending on the exposure risk:

• Type 3 (liquid-tight) – Guards against pressurised liquid sprays and jets, suitable for high-risk chemical handling or spill response.
• Type 4 (spray-tight) – Protects against low-pressure liquid aerosols or fine mist, ideal for cleaning, decanting, or industrial maintenance.
• Type 5 (particle-tight) – Shields against solid hazardous particulates such as asbestos, lead dust, or pharmaceutical powders.
• Type 6 (limited splash) – Offers low-level splash protection for light chemical or contamination risks.

For environments with ignition or thermal hazards, we also range flame-retardant and anti-static coveralls that meet EN 14116 and EN 1149 standards, reducing ignition risk while maintaining comfort, flexibility, and breathability.

Whether dealing with chemical sprays, fine particulates, or flammable atmospheres, pH7’s protective garments provide certified, full-body coverage to keep workers safe and compliant.

Both microporous film and SMS (Spunbond-Meltblown-Spunbond) non-woven fabrics are widely used in disposable protective coveralls, but they provide different levels of barrier performance, breathability, and strength depending on the application.

• Microporous film coveralls feature a laminated outer layer with microscopic pores that block liquid splashes, aerosols, and fine particulates while allowing limited moisture vapour transmission. Our SS200 microporous film coverall is an excellent choice when working with low hazard liquids such as paints, oils and fuels.  They are also suitable for use when dealing with asbestos or silica dusts and biological contaminants such as viruses and bacteria.
• SMS coveralls are made from three bonded polypropylene layers, combining strength, breathability, and particulate protection.  SMS is short from Spunbound, Meltblown, Spunbound. The meltblown middle layer filters out dry particulates and fibres, while the outer spunbond layers add durability and tear resistance. SMS garments are ideal for dusty environments and provide excellent protection against fine particulates including asbestos fibres and silica dust.  The coveralls are highly breathable making them more comfortable to wear for longer periods.

In summary, microporous coveralls offer superior liquid and chemical protection, while SMS coveralls prioritise breathability and comfort in dry environments.
