Contractor safety footwear: understand the range before choosing
This page contains three black safety-footwear entries whose source wording is mixed. UK 10 and UK 12 are steel-midsole D-ring chukka titles associated with reference 101SM, while UK 6 is Contractor CB104-6 Zircon. They must not be treated as one model in three sizes. Protection marking, declaration, construction and fit need verifying on the exact pair before workplace issue.
AutoMotoPart currently lists 3 Contractor safety footwear items. The largest Contractor safety footwear groups are 2 steel-midsole chukka size entries and 1 CB104 Zircon entry. Contractor safety footwear totals can change, so a category count is orientation rather than proof that a particular reference suits a vehicle, workplace or job. The exact Contractor safety footwear listing, its current technical information and the item in front of you must agree.
What the Contractor safety footwear page actually covers
| Product group in this range | Current entries | Selection focus |
|---|---|---|
| Steel-midsole chukka boots | 2 | Separate 101SM chukka UK 10/12 from CB104 Zircon UK 6; verify exact label/declaration, hazard marking, fit, tread and condition before issue. |
| CB104 Zircon safety boot | 1 | The unusual category wording is not footwear evidence; use the CB104-6 product reference, physical pair and current supplier documentation. |
Two entries are size variants of a steel-midsole chukka title; the third is CB104 Zircon in UK 6. The UK 10 and 12 records should be compared as the same 101SM family only after their labels agree. CB104's current S3 FO SC SR description belongs solely to CB104 and must not be copied onto 101SM.
Build a reliable shortlist
Document the hazards before choosing: toe impact/compression, underfoot penetration, wetness, hydrocarbon contact, slips, uneven ground, heat, cold, electrical work and ankle demands. Then identify which hazards are controlled elsewhere and which footwear markings are actually required.
| Check | Why it matters | Useful evidence |
|---|---|---|
| Exact model | 101SM chukka and CB104 Zircon have different construction and claims | Tongue/box label, product code and declaration |
| Standard edition | Marking systems changed between EN ISO 20345 editions | Full year, category and additional symbols on exact pair |
| Hazard | Toe, penetration, water, slip, heat and electrical risks are separate | Task assessment and supplier performance evidence |
| Fit | Poor heel hold, toe contact or pressure points reduce wearability and control | Both feet measured with work socks and walking trial |
| Surface | Laboratory slip classification cannot represent every contaminant | Trial on actual floor, tread cleaning and replacement plan |
| Condition | Impact, puncture, chemical or sole damage can defeat hidden protection | Pre-use checks, incident record and pair replacement |
If the physical boot says only ‘S1’ while a title says steel midsole, or a listing and declaration disagree, do not infer penetration protection. Isolate the pair and obtain current product documentation from the supplier. The highest-looking code is not a substitute for traceable marking.
Separate the 101SM chukka from CB104 Zircon
The chukka listings are UK 10 and UK 12 with source dimensions of 330 × 220 × 120 mm and 360 × 230 × 120 mm respectively; those carton-like measurements are not foot dimensions. A published safety-footwear price list identifies 101SM as a Contractor black chukka and marks it S1P SRC, while the live text says S1 and mentions a steel midsole. That inconsistency requires label and declaration verification rather than editorial correction.
CB104-6 is UK 6 and carries the distinct Zircon name. A current supplier record gives EN ISO 20345:2022 S3 FO SC SR for CB104. BSI confirms BS EN ISO 20345:2022 is the current safety-footwear standard, but product compliance remains a claim that must be supported by the exact pair's marking and documentation—not by this collection page.
Understand the verified CB104 marking without overextending it
S3 is a combined category within the 2022 standard, while FO, SC and SR are additional marks described in the current supplier record. Use the manufacturer's declaration and instructions for their complete test meanings and limitations. A laboratory result does not promise protection against every real workplace object, liquid or surface.
Water-resistant upper wording is not the same as a waterproof boot for immersion. Antistatic footwear manages charge within a defined resistance range; it is not dielectric footwear and must not be chosen for live electrical work. A scuff-cap mark concerns abrasion at the toe area, not impact protection beyond the safety-toe category. Keep each claim within its declared test.
Fit UK 6, 10 or 12 to the wearer—not the title
Measure both feet late enough in the day to account for normal swelling and use the socks, orthoses and trousers intended for work. Lace the boot fully and check toe clearance, width over the forefoot, heel retention, instep pressure and ankle movement. Walk, turn, climb and crouch in a clean trial area; toes must not strike the cap and the heel should not lift excessively.
Do not solve a poor fit by cutting the lining, omitting laces, crushing the heel counter or adding an unapproved thick insole that changes toe clearance or antistatic performance. HSE says PPE must suit the worker's size and physical characteristics and should not be modified to fit. Where no listed size/last is suitable, select another certified model.
Match sole and protection to the workplace
Map the real walking surfaces: smooth concrete, tiles, chequer plate, ladders, mud, swarf, water, oil or food residue behave differently. HSE notes that oil-resistant means the sole material resists oil damage, not that it will be slip-resistant on an oily floor. Clean clogged tread and trial footwear on representative surfaces and contaminants.
A steel midsole may be inappropriate around some detection systems or specialist electrical/magnetic work, while a general chukka may not cover molten metal, chainsaw, foundry, chemical or extreme-temperature hazards. Use footwear designed and marked for those tasks. Safety boots do not replace housekeeping, spill removal, guards or safe material handling.
Inspection, cleaning and replacement
Check pairs before first issue against their box, label and declaration; do not mix left and right boots from different models or sizes. Before each use inspect for cuts, crushed toe area, puncture, split sole, worn tread, loose stitching, damaged D-rings and contamination inside. Remove stones or swarf without pushing them further through the sole.
Clean and dry by the footwear maker's instructions, away from direct heat that can crack uppers or damage bonds. Store as a pair in a dry ventilated place. After a dropped load, sharp-object strike, chemical splash or heat exposure, quarantine and replace unless a competent assessment and maker's instructions support continued use. Do not wait for visible steel or a hole.
From identification to a checked result
| Stage | Good practice for this range | Mistake to avoid |
|---|---|---|
| Assess | Control hazards first, then specify required footwear performance | Buying from the word safety without a task assessment |
| Identify | Confirm 101SM or CB104, size, standard year and full marking | Copying CB104 S3 symbols onto chukka boots |
| Fit | Trial both feet with work socks and normal job movements | Modifying PPE or accepting toe/heel pressure |
| Use | Lace correctly, keep tread clean and use with compatible PPE | Treating oil resistance as universal slip protection |
| Inspect/replace | Check each shift and quarantine after impact, puncture or chemical damage | Wearing until the toe cap or midsole is visibly exposed |
Record wearer, model/reference, UK size, full marking, issue date and inspection/replacement events. Keep a copy or route to the declaration and instructions. This prevents a size-only stock record from concealing which protection family was actually issued.
Reading real Contractor safety footwear references
The Contractor safety footwear names below are examples from the current range and show why the complete description matters. They are not universal Contractor safety footwear recommendations and should not be treated as a fitment list. Within Contractor safety footwear, a shared family word can conceal a different dimension, connector, material, pack format, operating condition or installation side.
| Example listing | What to verify beyond the name |
|---|---|
| Safety Chukka Boots (Steel Midsole) - Black - UK 10 | 101SM-style chukka UK 10, exact label/declaration, steel-midsole claim and wearer fit |
| Safety Chukka Boots (Steel Midsole) - Black - UK 12 | 101SM-style chukka UK 12, same family evidence, full marking and surface trial |
| Contractor CB104-6 Zircon Black Safety Boot - UK 6 | CB104-6 Zircon UK 6, current EN ISO 20345:2022 S3 FO SC SR supplier claim and exact-pair verification |
The size number does not identify protection. Preserve 101SM versus CB104-6 and never infer that UK 6 is simply the smaller version of the UK 10/12 chukka.
Common errors around Contractor safety footwear products
- Treating all three listings as one boot model in UK sizes 6, 10 and 12.
- Copying CB104's current S3 FO SC SR description onto the 101SM chukka.
- Assuming a steel-midsole title proves a specific penetration marking without the label.
- Reading antistatic as electrical insulation or oil-resistant as slip-proof.
- Choosing by length alone without width, heel hold and movement trial.
- Modifying the insole, lining, laces or upper to force a poor fit.
- Using general safety boots for foundry, chainsaw, chemical or live-electrical hazards.
- Continuing after significant impact, puncture, sole separation or chemical/heat damage.
Contractor safety footwear questions and answers
Q: Which Contractor footwear is listed?
A: Steel-midsole black chukka titles in UK 10 and 12 plus CB104-6 Zircon in UK 6.
Q: Are all three the same model?
A: No. The UK 10/12 chukkas align with 101SM wording, while UK 6 is the distinct CB104 Zircon.
Q: What standard is current in the UK source?
A: BS EN ISO 20345:2022 is current; only the CB104 supplier record here explicitly states that edition.
Q: What is CB104 currently marked as?
A: The current supplier record states EN ISO 20345:2022 S3 FO SC SR; confirm it on the exact pair and declaration.
Q: Can that marking be applied to the chukka boots?
A: No. Their S1 versus S1P/SRC records conflict, so check the physical label and documentation.
Q: Does steel midsole wording prove all puncture protection?
A: No. Verify the declared marking and recognise that tests cannot cover every object, angle or force.
Q: Are antistatic boots safe for live electrical work?
A: No. Antistatic is not electrical insulation; use specialist footwear and an approved electrical system of work.
Q: Does an oil-resistant sole prevent slips on oil?
A: No. HSE says oil resistance concerns material durability, while slip performance depends on surface, contaminant and tread.
Q: How should size be selected?
A: Measure both feet and trial the exact model with work socks through walking and job movements.
Q: Can an extra insole improve a loose fit?
A: Only use an insole configuration authorised for that footwear, because protection and fit can change.
Q: When should boots be replaced?
A: After protection-threatening impact, puncture, chemical/heat damage, sole separation, deep cuts or unsafe tread wear.
Q: Does safety footwear remove the workplace hazard?
A: No. It supplements engineering, handling, housekeeping and safe-working controls identified by the risk assessment.
