Shanghai Zimai Safety Technology Co. , Ltd.
Before you buy Hi-Vis Vests in bulk, what should you check? Color brightness alone is not enough.
ZIMAI Shanghai Zimai Safety Technology Co., บจ. has been exporting PPE for over 30 ปี. Its vests illustrate what should be covered in a hi vis safety vest buying guide. Verify the class, cloth, tape, ขนาด, and documents. If one of these is weak, the buyer might be in trouble.
A decent export vest demonstrates its visibility class. It features a bright fluorescent cloth basis. The reflective tape is at least 50mm broad. Sizes for the whole crew. Ask the provider for documents for your precise model before you purchase.
A Hi Vis Safety Vest Buying Guide for Importers: Five Checks Before You Order
Five checks tell you if a vest is ready for export. Look at each one.
- ระดับ: the visibility level the vest lists.
- ผ้า: the bright base layer.
- เทป: how wide it is and where it sits.
- การปรับขนาด: the full range, with ladies’ ขนาด.
- Papers: certificates and export record.
A vest that passes all five is a safer buy.
What Do Visibility Classes Mean on a Vest Label?
Visibility grades indicate the amount of bright and reflective material on a garment. ใน ISO 20471:2013 defines three classifications of High visibility clothing in high-risk circumstances must meet this international standard. The tape on these clothing should be not less than 50 mm broad.
The highest level is class 3. ระดับ 1 is the lowest one. In your personal risk evaluation you choose the appropriate class. For road work the ZIMAI standards website links to UK road-work advice.
Class Table for EN ISO 20471
| ระดับ | ระดับ | นาที. วัสดุพื้นหลัง | นาที. วัสดุสะท้อนแสงย้อนยุค |
| ระดับ 3 | Highest level | 0.80 ตร.ม | 0.20 ตร.ม |
| ระดับ 2 | Middle level | 0.50 ตร.ม | 0.13 ตร.ม |
| ระดับ 1 | Low level | 0.14 ตร.ม | 0.10 ตร.ม |
The ZIMAI pages for HV001, HV002, HV003, HV005, HV007 and HV015 list EN ISO 20471:2013 คลาสที่สอง. That is the same as Class 2 in the table above.
Which Fluorescent Fabric Should You Ask For?
The brilliant base layer of a vest is made from fluorescent cloth. It helps people notice the person in daytime.
Standard ZIMAI vests are made from 120 gsm polyester knit fluo cloth. มันมี 155 ผ้าเรืองแสงถักโพลีเอสเตอร์หน่วงไฟแกรม. Both are available in Hi-Vi Orange and Hi-Vi Yellow.
gsm indicates grams per square meter. Ask each provider to write down the fabric type, น้ำหนัก, and color name. The weight lets you compare two quotations.
เทปสะท้อนแสงควรกว้างแค่ไหน?, and Where Does It Go?
Reflective tape should be at least 50 mm wide under EN ISO 20471. ZIMAI vests use 5 ซม. เทป. That is the same as 50 มม.
Tape Position by Model
- HV001, HV005 and HV015: shoulder and waist
- HV002: waist only
- HV003: segmented tape on shoulder and waist
- HV007: flame retardant tape on shoulder and waist
- HV006: 5 ซม. เทป, but its page lists no position
The placement of the tape affects the appearance of the worker from the side and from behind. Choose the spot that matches the job. Cut into small lengths (like on the HV003): Segmented tape It isn’t a lengthy strip.
How Do Day and Night Visibility Work Together?
High visibility apparel is effective for two reasons. Fluorescent fabric works in daylight. Reflective tape is great in the dark.
You may see the similar division in EN 17353:2020 on the ZIMAI standards site. There are three kinds of gear in that specification.
Types in EN 17353
- Type A: for daylight only. It uses fluorescent material alone.
- Type B: for the dark only. It uses retroreflective material alone.
- Type AB: for day, dusk and dark. It uses both materials.
ZIMAI vests contain luminous fabric and reflective tape. This is good for work that goes from daylight to evening.
How Do You Handle Vest Sizing for a Mixed Crew?
ZIMAI vests available in sizes S-5XL. The HV006 Reflective Harness is available in Men’s and Ladies’ sizes.
A mixed crew need the whole range in each order. Not everyone will be in middle sizes. No body measurements are given on the site. Before deciding how many of each size to purchase ask for a sizing chart.
Which Vests Have Extra Features?
Some tasks demand more than just a basic vest. The HV003 and HV005 are multi-pocket models. No information about pockets on their pages. The HV015 is a double color vest. The HV007 is constructed of flame retardant fabric and adhesive. The HV800 is designed for cold weather.
