I’ve been thinking about carrying out some modifications to my helmet’s shell such as drilling some ventilation holes and rigging up some kind of lamp on the front. Is this likely to affect my helmet’s effectiveness? Yes, it would definitely affect the performance.

In use, head protection is generally treated with a lack of care, often being thrown or dropped, used as a receptacle for all manner of items, or carried on the rear window shelf of a vehicle.

The harness is an integral part of all Invincible™ helmets and works by stretching which absorbs some of the energy of the impact. The harness also spreads the force of an impact evenly over the wearers head minimising the risk of harm to the user. How does a helmet protect me from falling objects?

HHeeaadd PPrrootteeccttiioonn QQuueessttiioonnss aanndd AAnnsswweerrssCCaann II AAppppllyy LLaabbeellss??Many of our customers wish to puttheir own design of self-adhesivelabels on our range of industrialSafety Helmets.
The instructions supplied with eachand every helmet states:
““DDoo nnoott aappppllyy ppaaiinntt,, ssoollvveennttss oorrsseellff--aaddhheessiivvee llaabbeellss eexxcceepptt iinnaaccccoorrddaannccee wwiitthh iinnssttrruuccttiioonnss ffrroommtthhee hheellmmeett mmaannuuffaaccttuurreerr””Suitability of a self-adhesive labelcan only be determined by carryingout tests over the expected life of ahelmet and could therefore take several years.
We can therefore not guarantee the performance of our productswhen material other than that usedand tested by JSP Ltd is used tomodify a helmet’s appearance.

IIsstthhiiss ttrruuee??No they are made to two differentstandards and serve two differentpurposes. The Top Cap is a bumpcap that provides safety head protection to EN812:1997 standard. It is not designed to protect the wearer from fallingmasses. The industrial safety helmet provides head protection toEN397:1995 and is designed toprotect the wearer from fallingmasses.

• Number of European Standard e.g: (EN397:1995)
• Year and quarter of manufacture
• Year of American ANSI Standard Z89.1-2003 (or 1997)
WWhhaatt iiss tthhee sshheellff lliiffee ooff aann iinndduussttrriiaall ssaaffeettyy hheellmmeett??If the helmets are stored in theboxes in which they were suppliedand do not experience environmental extremes the shelf life of a helmet is not limited.
We would not expect a helmet tobe in use more than five years afterthe date of manufacture.
Storage conditions should bebetween 5°C and 50°C and relativehumidity less than 75%.

It is made of polycarbonate and canbe obtained in clear or anti glare. Itfits directly onto the helmet andretracts inside the shell when not inuse. The Retractaspec meets the requirements of EN166.1.F (Low energy impact).
