General rules for the use of protective barriers (fragment)



The protective safety barrier is a road safety device, but it is also a physical obstacle which, if hit by a vehicle, may pose a threat to the health or life of road users.The main purpose of using road safety barriers is to protect the health and life of road users  and the safety of persons and structures in the vicinity of the road.


Protective barriers may only be used if their absence could have more negative effects on persons in the vehicle and on persons and objects in the hazardous safety barrier area than in the case of barriers. After identifying the presence of hazards on the road and its surroundings that require the use of safeguards, it is necessary.




To check the safety barrier possibility of removing, moving or minimizing these hazards by engineering activities (e.g. changes in the location of obstacles, the use of supporting structures absorbing energy or easily tearable during impact, barrier alleviation of slope inclination and sharpening of sharp edge,Solutions that pose hazards that will require the use of protective barriers should be avoided on existing roads or in their vicinity. 

Such action would be contrary to the logic and principle of minimizing threats.For single obstacles that cannot be eliminated, or for a traditional support structure that cannot be replaced by an energy-absorbing or easily breakable safety barrier structure, it should be considered whether protective barriers or crash cushions will be more effective and economical for their protection.

Safe use of forklifts in a warehouse

Image
Basic obligations of the employer. The safe and proper use of forklift safety barriers warehouse equipment, including forklifts or shelves, should be remembered at the planning stage of warehouse equipment. - Currently produced forklifts are devices with a rather complicated construction, equipped with many additional functions and very technologically advanced.Therefore, their efficient operation requires both knowledge and practical experience.Unfortunately, as everyday practice shows, employers are often unable to choose the right type of wheelchair for the type of work performed and the specificity of the workplace. And this causes difficulties after buying, and in extreme cases it can increase the likelihood of possible accidents at work. Absolutely necessary to submit a device for  forklift safety barriers  technical examination in writing in the appropriate technical inspection unit. The decision to operate the truck is only issued after completing this procedur

Why choose our protective barriers?

Image
Avoid machine collisions against walls, corners, shelving units, poles and pipes with our range of warehouse protection barriers Suitable for warehouses, factories, public buildings or office buildings, the range can be used indoors and outdoors. Manufactured from hot-dip galvanized steel for durability, our uprights are also powder coated in RAL 1021 color for added visibility. The range of warehouse protection barriers have been designed and tested in accordance with standard NF EN 15512: 2009. The standard states that a vertical guard must be placed at the end of each row of shelving between the cross aisles and at the uprights, which are located at the intersections of the aisles and walkways. The uprights of the protective barriers all have a minimum height of 400 mm and dynamic tests have been carried out to ensure a minimum energy absorption of 400 Nm. Finally, verge safety barriers are modular systems, which makes them economical, easy to install and to replace in the event of

Road safety: Andromeda, the intelligent safety barrier

Image
Safer roads A revolutionary safety barrier that signals the danger in advance, and due to its shape it is particularly safe for motorcyclists in the event of an impact. It is called Andromeda and has been studied by SMA Road Safety, a company from Marcianise (CE) that operates in the field of passive road safety through the design and construction of impact attenuators, road barriers and monitoring devices; his most important interventions include the Eurasia Tunnel in Istanbul, the fourth longest bridge in the world in Kuwait, the redevelopment of motorways in Romania, Greece, Qatar and other nations. The new Andromeda barrier, presented on the occasion of a technical seminar promoted in collaboration with the Province of Ancona, is defined as the first light smart safety barrier   available on the market and consists of transparent PET panels, inserted at a minimum distance from the ground and framed by circular metal profile poles for the benefit of safety for motorcycl
