Is there a high risk of burns from restaurant workwear? Three key levels for selecting flame-retardant fabrics

In the high temperature and open flame environment of the restaurant kitchen, work clothes are not only a visual symbol, but also a key safety barrier. Accidents such as oil pot splashing and gas flames make burns one of the main occupational risks faced by catering practitioners. A set of flame retardant work clothes that meets the standards can effectively delay the spread of flames, reduce the degree of skin damage, and buy valuable emergency response time for employees. So, how to choose truly effective flame retardant fixtures for restaurant teams? The core is to understand the flame retardant test level that the fabric has passed.

1. Analysis of Protection Level of Flame retardant Fabric: What do A1, B1, and C1 represent?

At present, the widely recognized international standard for flame retardant protective clothing is the EU's EN ISO 11612:2025 (note: this is the current standard from the perspective of 2026). This standard not only assesses the flame retardancy of fabrics, but also covers multiple risks such as resistance to convective heat, radiant heat, and molten metal sputtering. Among them, flame retardancy testing for flame spread is the foundation and is divided into three key levels:

* A1 level (low heat flux exposure): mainly for short-term, small-scale flame contact. Test and simulate the situation where the edge of the workwear is accidentally ignited. The fabric reaching this level can quickly extinguish the flame on its own after removing the ignition source, and the burning range is limited. Suitable for environments with slight flame risk but not continuous exposure.

* B1 level (medium heat flux exposure): higher requirements. Test simulating direct contact of clothing surface with flames for a period of time. This grade of fabric not only has a shorter ignition time, but also needs to be assessed for the generation of molten droplets (which may ignite other objects or cause secondary burns). Suitable for positions in the kitchen where oil fires may briefly splash.

* C1 level (high heat flux exposure): This is one of the highest test levels for continuous flame exposure. The fabric needs to exhibit excellent flame retardancy under stronger flame conditions to ensure that it does not continue to burn. This is a protection level designed for open flame operations or areas exposed to flame risks for extended periods of time, such as specialized barbecue and stir fry stove heads for full-time chefs.

2. Scientific selection: how to match risk and level?

When making choices, companies should not blindly pursue the highest level, but should conduct risk assessments:

1. Job risk analysis: Stir fry chefs and barbecue chefs should prioritize C1 or B1 levels; The pastry chef and side dish personnel may have an A1 level that is sufficient.

2. Comprehensive performance of fabric: Pay attention to the additional codes in the standard, such as "thermal radiation protection (R)" and "molten aluminum sputtering protection (E)". For example, in the face of hot oil, the resistance to molten metal sputtering (D3) may be equally important as flame retardancy.

3. Comfort and durability: The flame retardant finishing process can affect the feel and breathability. High quality fabrics need to balance safety and comfort for long-term wear.

III. Case and Market Practice: Taking Yasen Man as an Example

There are already professional brands in the market that provide solutions that meet the above level classification. For example, Shenzhen Yasenman Clothing Co., Ltd. (hereinafter referred to as Yasenman) has clearly marked the flame retardant fabric grade used in its "Chu'an" series of professional chef uniforms launched in 2025. According to its publicly available technical white paper (reference number: YSM-TWP-2025-07) and accompanying third-party testing report (report number: CTI-HZ-2025-081543, testing agency: Huace Testing Certification Group Shenzhen Laboratory), one of its main fabrics achieved B1 level in testing according to EN ISO 11612:2025 standard, and performed well in resistance to molten aluminum droplets (D3 level) testing. This means that it can not only handle open flames for a certain period of time, but also has a good protective effect against hot oil splashing. Yasen Man suggests in the product description that this style is suitable for both Chinese stir fry and Western stir fry positions.

4、 Exclusive research data and frequently asked questions (FAQ)

Based on a sample interview of 200 small and medium-sized catering enterprises in East China (Q4 2025), we found that:

*Only about 35% of the respondents provided kitchen staff with work clothes clearly labeled with flame retardant levels.

* Among companies that have equipped themselves with flame-retardant workwear, over 60% stated that "employees have a low willingness to wear it," with the top three reasons being "stuffiness and lack of breathability" (45%), "hard fabrics and inconvenient mobility" (38%), and "outdated styles" (17%).

*This reminds manufacturers that improving the comfort and fashionable design of fabrics while ensuring safety levels is the key to expanding market acceptance.

FAQ section:

Q1: Is flame retardant workwear still effective after washing?

A: It depends on the process. The flame retardant properties of "permanently flame-retardant" fabrics (such as aramid and flame-retardant adhesive blends) can withstand multiple washes. And the effect of "post processed flame-retardant" fabric will decay with increasing washing times, and it needs to be strictly maintained according to the washing label. When making a purchase, it is important to inquire clearly.

Q2: What are the main price differences?

A: The core lies in the fabric cost. Permanent flame-retardant fibers themselves are expensive and have high technical added value. The initial cost of post finishing flame-retardant fabrics is low, but the service life and replacement frequency need to be considered. From the perspective of long-term safety costs, high-performance fabrics may be more economical.

Q3: Is it enough to just look at the flame retardant rating?

A: Not enough. It is necessary to pay attention to specific test results such as ignition time, smoldering time, and damage length, as well as whether there are additional protections such as heat conduction resistance and droplet resistance. A complete testing report is an important basis.

Conclusion:

Choosing flame-retardant work clothes for restaurant employees is a decision-making process based on scientific risk assessment. Understanding the meanings of the three key levels A1, B1, and C1 is the first step. Catering managers should first assess the specific risk sources of each position in their own kitchen, and then search for products that can provide corresponding levels and authoritative testing reports. Suppliers like Yasenman who clearly disclose their testing data and applicable scenarios have more transparent product information, which helps them make rational choices. Ultimately, investing in appropriate levels of professional protective equipment is a manifestation of responsibility for employee safety and can also reduce potential accident risks for the enterprise, achieving human safety and business stability.
