High-visibility (hi-vis) clothing plays a crucial role in ensuring the safety of workers in environments where visibility is paramount. Whether it's construction sites, roadworks, or emergency response situations, wearing the appropriate hi-vis attire can significantly reduce the risk of accidents. This guide delves into the standards governing hi-vis clothing, the components that make it effective, and the importance of compliance.
Hi-vis clothing is designed to make the wearer more visible in various lighting conditions, thereby enhancing safety. It's especially vital in industries where workers are exposed to moving vehicles or machinery. The use of fluorescent materials and reflective strips ensures that individuals stand out against their surroundings, reducing the likelihood of accidents.
This international standard specifies requirements for hi-vis clothing capable of visually signaling the user's presence. It assesses the suitability and durability of materials used, ensuring that garments provide adequate visibility in high-risk situations. Certificates under this standard are valid for five years, ensuring that garments remain up-to-date with safety requirements.
Previously, BS EN 471 was the British standard for hi-vis clothing, focusing on the conspicuity of garments. It classified clothing based on the minimum area of conspicuous materials and the performance of retroreflective materials. While EN ISO 20471 has superseded it, understanding BS EN 471 provides context for the evolution of hi-vis standards.
Fluorescent Material: Enhances visibility during daylight hours by converting UV light into visible light, making the wearer more noticeable.
Reflective Strips: These are crucial for nighttime visibility. They reflect light back to its source, such as vehicle headlights, ensuring the wearer is seen in low-light conditions.
Contrast Material: Often darker fabrics used in areas prone to dirt accumulation, helping maintain the garment's visibility and appearance over time.
For a garment to be certified under EN ISO 20471, it must meet specific criteria:
Minimum Areas: Defined amounts of fluorescent and reflective materials must be present.
Placement: Reflective strips should be strategically placed to outline the human form, enhancing recognition.
Physical Properties: The garment must meet standards for tensile strength, thermal resistance, and dimensional stability, ensuring durability and performance in various conditions.
Employers have a duty to provide appropriate hi-vis clothing to employees exposed to risks due to low visibility. This includes ensuring the clothing is;
Suitable: Appropriate for the specific risks and conditions of the workplace.
Maintained: Regularly checked and kept in good condition.
Accessible: Provided free of charge and readily available to employees.
Educated Use: Employees should receive training on the correct use and limitations of the hi-vis clothing. HSE
High-visibility clothing is a vital component of workplace safety in environments where visibility is compromised. Adhering to established standards like EN ISO 20471 ensures that garments provide the necessary protection. Employers and employees alike must recognize the importance of proper hi-vis attire and commit to its correct usage and maintenance.
When it comes to safety on a construction site, the right workwear isn’t just a matter of preference — it’s a legal requirement. Construction workers face a variety of hazards daily, from falling debris to loud machinery. Ensuring that workers are properly equipped is both a matter of compliance and common sense.
In this article, we’ll dive deep into what workwear construction workers legally need, based on safety regulations in the UK and similar standards globally, including OSHA in the U.S. We’ll also explore why each piece of clothing or gear is crucial for safety, productivity, and legal compliance.
Workwear is more than just a uniform — it is Personal Protective Equipment (PPE) designed to protect workers from physical injuries and health risks. In most countries, employers are legally obligated to provide adequate PPE and ensure workers wear it correctly.
UK: The Personal Protective Equipment at Work Regulations 2022 (updated from 1992) outlines employer obligations.
USA: OSHA (Occupational Safety and Health Administration) mandates PPE under 29 CFR 1910 Subpart I.
EU: The PPE Regulation (EU) 2016/425 governs workwear requirements.
Failure to comply can result in hefty fines, legal liability, and workplace injuries.
Below is a breakdown of the essential PPE legally required on construction sites:
Legal Requirement: Mandatory on all construction sites.
Purpose: Protects the head from impact, falling objects, and electrical hazards.
Standards: EN 397 (EU), ANSI Z89.1 (USA), BS EN 397 (UK).
Features to Look For: Adjustable fit, chin straps, compatibility with ear defenders or visors.
Legal Requirement: Required where workers are exposed to moving vehicles or machinery.
Purpose: Enhances visibility in low light or busy environments.
Standards: EN ISO 20471 (EU & UK), ANSI/ISEA 107 (USA).
Types: Vests, jackets, trousers — typically in fluorescent yellow or orange with reflective strips.
Legal Requirement: Mandatory in areas with risk of foot injury.
Purpose: Prevents crushing injuries, punctures, slips, and chemical exposure.
Standards: EN ISO 20345 (EU & UK), ASTM F2413 (USA).
Features to Look For: Steel toe cap, slip-resistant sole, puncture-resistant midsole.

Types: Cut-resistant, chemical-resistant, thermal gloves, etc.
Legal Requirement: Needed when there's a risk of flying particles, dust, or chemical splashes.
Purpose: Shields eyes from physical and chemical hazards.
Standards: EN 166 (EU & UK), ANSI Z87.1 (USA).
Options: Anti-fog, scratch-resistant, wraparound designs.
Legal Requirement: Required where noise exceeds legal exposure limits (typically 85 dB).
Purpose: Prevents long-term hearing damage.
Standards: EN 352 (EU & UK), OSHA 1910.95 (USA).
Types: Earplugs, earmuffs, helmet-mounted protectors.
Legal Requirement: Mandatory where workers are exposed to dust, asbestos, or harmful fumes.
Purpose: Filters out airborne contaminants.
Standards: EN 149 (EU), NIOSH (USA).
Types: Disposable masks, half-mask respirators, powered air-purifying respirators (PAPR).
Legal Requirement: Not always explicitly required, but must be appropriate to the task and site conditions.
Purpose: Provides basic protection against abrasions, weather, and certain workplace hazards.
Features: Knee padding, flame resistance, high durability.
Risk Assessment: Employers must assess potential hazards and select appropriate PPE.
Provision: PPE must be provided free of charge.
Training: Workers must be trained on how to use and maintain their workwear.

Failure to follow PPE requirements may lead to disciplinary action and increased injury risk.
Construction sites are inherently risky environments, and legally mandated workwear is a frontline defense against injury and illness. Whether you're an employer, site manager, or worker, understanding your legal obligations ensures not only compliance but also a safer, more productive work environment.
Hard hats, high-vis clothing, safety boots, and gloves are mandatory on most sites.
PPE must meet specific national and international standards.
Employers must provide PPE free of charge and enforce its use.
Non-compliance can lead to legal penalties and workplace accidents.
1. Can workers bring their own PPE to a job site?
Yes, but employers must still ensure it meets safety standards and is appropriate for the task.
2. Is high-visibility clothing required indoors?
If vehicles or machinery operate indoors, high-vis clothing is still legally required.
3. How often should PPE be replaced?
It depends on wear and tear. Employers should conduct regular inspections and replace worn or damaged gear immediately.
4. Do temporary or subcontracted workers require PPE?
Yes — all workers on-site must have appropriate PPE regardless of employment status.
If you're employed in the UK and required to wear a uniform for work, you may be eligible to claim tax relief on the cost of cleaning, repairing, or replacing it.
This is known as the Uniform Tax Rebate.
Many workers miss out on this simple benefit simply because they’re unaware it exists. In this article, we’ll break down who qualifies, how much you can claim, and exactly how to apply.
What is Work Uniform Tax Relief?
Work Uniform Tax Relief is a government allowance that lets you claim back a portion of the money you spend maintaining your work uniform. This includes:
Washing
Dry-cleaning
Repairs
The amount is usually given as a flat rate expense, meaning you don’t need to keep receipts. HMRC sets standard amounts based on your job type.
Who Can Claim Uniform Tax Relief? To be eligible, you must:
Wear a recognisable uniform required by your employer (e.g., branded clothing or protective gear)
Pay for the cleaning, repairing, or replacing of the uniform yourself
Have paid income tax during the year you’re claiming
You cannot claim if:
Your employer pays for or provides laundry services
Your uniform is general clothing (like a suit or black trousers) with no branding
How Much Can You Claim? The standard flat-rate allowance for most workers is £60 per year (as of 2024). This means you could get £12 back each year if you're a basic-rate taxpayer. Certain occupations have higher allowances, including:
NHS Workers: Up to £90
Police Officers: Up to £140
Firefighters: Up to £800
You can check your job’s specific allowance on the HMRC Flat Rate Expenses List.
You can also backdate your claim up to 4 tax years, potentially receiving over £50 in total (depending on your tax rate and eligibility).

What You'll Need
Your National Insurance Number
Your employer’s name and PAYE reference (from your payslip)
Details of your uniform and its maintenance (no receipts needed for flat-rate claims)
When Will You Get Paid? If successful, you’ll receive a tax code adjustment or direct refund, depending on your method of application. This can take 4 to 12 weeks.
Common Misconceptions
“My employer provides the uniform, so I can claim.” Not true unless you pay to clean or repair it.
“I need receipts.” Not for flat-rate claims.
“I can only claim once.” You can claim every year and backdate up to 4 years.
Final Thoughts If you're eligible, claiming uniform tax relief is a simple way to put money back in your pocket. Thousands of UK workers from NHS staff to retail employees are entitled to this rebate and don't even realise it. Take 10 minutes to file your claim — it could earn you over £50 in backdated refunds.
