Applications and use cases
The 3M™ 2845 welding shade 5 safety glasses are intended for professional and industrial environments where shade 5 eye protection is required for specific welding-related operations. The following applications are based on verified information for the 2840 Series with the 2845 shade 5 lens:
- Gas welding (oxy-acetylene) within the recommended operating range for shade 5 filters.
- Oxy-fuel cutting (oxicorte), where shade 5 is appropriate for the process and parameters used.
- Construction work involving hot work tasks compatible with shade 5 requirements.
- Automotive workshops and metal fabrication where gas welding or cutting is performed.
- General manufacturing environments requiring protection from high-speed, low-energy particles and radiation in the shade 5 range.
- DIY and maintenance work involving compatible welding and cutting tasks, provided that all applicable regulations and risk assessments are followed.
Use outside these verified applications, especially for electric arc welding or grinding, is not recommended by 3M and may not provide adequate protection.
FAQ
1. Are these safety glasses suitable for MIG, TIG or stick welding?
No. According to the 3M technical sheet for the 2845 lens, this product must not be used for electric arc welding processes such as MIG, TIG, stick (electrode) or plasma cutting. A dedicated welding helmet or shield certified for these processes is required.
2. Can I wear these over my prescription glasses?
No. The 3M 2845 safety glasses are not designed to be worn over prescription spectacles. If over-the-glasses protection is required, a specific OTG (over-the-glasses) model from 3M should be selected.
3. Do the lenses have anti-fog and anti-scratch coatings?
Yes. For the 3M 2845 model, the technical data confirms an anti-scratch (AS) and anti-fog (AF) coating to help maintain clear vision and extend lens life. Actual performance depends on conditions and maintenance.
4. What level of impact protection do these glasses provide?
The glasses are certified to EN 166:2001 with a 1 FT marking, meaning optical class 1 and protection against high-speed, low-energy particles at extreme temperatures.
5. Are these glasses CE marked?
Yes. The 3M 2840 Series, including model 2845, complies with the essential safety requirements of the European PPE Directive and bears the CE mark.
6. Can I use these glasses for grinding operations?
No. The 3M documentation specifies that these products are not suitable for grinding. For grinding operations, eyewear or face shields specifically certified for that risk must be used.
7. Are they comfortable for long periods?
The glasses are lightweight (around 26 g) and include an adjustable, pivoting temple design plus a soft internal pad, features intended to improve comfort during extended use. Comfort perception can vary by user.
8. Do these glasses protect against UV and IR radiation?
Yes. The shade 5 lens offers 99.9% UV absorption and approximately 99.5% IR absorption (780–1100 nm), in line with its classification as a welding shade 5 filter under EN 169.
9. Is the "SecureFit" and "goggles" naming in the title officially confirmed for this model?
Based on the available 3M technical documentation, model 2845 is part of the 3M 2840 Series of safety glasses and is not explicitly listed under the SecureFit or goggle product ranges. Any reference to "SecureFit" or "goggles" in the title above should therefore be considered unverified and may reflect a local or commercial naming rather than the official 3M classification.
Section 14 – Transport information
The 3M™ 2845 welding shade 5 safety glasses are non-powered personal protective equipment made mainly of polycarbonate and thermoplastic materials. Under normal conditions of use and transport, they are generally handled as non-dangerous consumer/industrial goods. No specific hazard-based transport classification (such as ADR, IMDG or IATA dangerous goods regulations) is indicated in the consulted technical documentation.
Packaging is typically designed to protect the eyewear from mechanical damage, dust and moisture during storage and transport, but exact packaging formats, quantities per box and palletisation details are not specified in the available sources and should be considered unverified.
Before large-scale shipment or integration into logistics systems that require formal classification, users and distributors should review the latest official 3M technical documentation or, if applicable, the product’s safety or transport data provided directly by 3M.
Section 8 – Individual protection measures
This section summarises how the 3M™ 2845 welding shade 5 safety glasses fit within a wider personal protective equipment (PPE) strategy. The points below combine verified performance data for the eyewear with general best practice for welding and hot work tasks; any details not stated in 3M documentation should be treated as indicative only.
8.1 Eye and face protection
- Use the 3M 2845 safety glasses specifically for tasks where a welding shade 5 filter is appropriate, such as gas welding and oxy-fuel cutting, within the limits defined by applicable standards and 3M guidance.
- Do not use these glasses for electric arc welding or grinding; in those cases, use correctly rated welding helmets/shields or grinding visors.
- Ensure glasses sit close to the face with the temple length and angle correctly adjusted to minimise gaps and maximise coverage, including the integrated upper protection.
- Inspect lenses regularly for scratches, cracks, or coating damage; replace the product if defects are found or if visibility is compromised.
8.2 Hand, body and respiratory protection (contextual information)
- For welding and cutting tasks, combine the eyewear with suitable heat- and cut-resistant gloves, flame-resistant clothing and, where required, welding aprons or jackets, in accordance with your risk assessment and applicable standards.
- When fumes, gases or dust may exceed occupational exposure limits, use appropriate respiratory protection (for example, filtering half masks, reusable respirators or powered air systems) selected and fitted according to the manufacturer’s instructions and local regulations. The exact compatibility of this eyewear with specific respiratory models is not verified and should be checked with 3M guidance.
- In noisy environments, use suitable hearing protection (earplugs or earmuffs) in addition to eye protection, as required by noise measurements and regulations.
8.3 General safety measures
- Always conduct a task-specific risk assessment to determine the appropriate combination of PPE.
- Train users on correct donning, adjustment, cleaning and storage of the 3M 2845 safety glasses.
- Store the glasses in a clean, dry case or pouch to protect the lens coatings from scratches and contamination.
- Follow local legislation and company procedures regarding PPE selection, maintenance and replacement intervals.
For full and up-to-date information on limitations of use, compatibility with other PPE and detailed performance data, users should refer to the latest official 3M technical datasheet for model 2845.
