Collective protection
The term collective protection refers to a form of fall protection for people, which, in contrast to personal protective equipment against falls (PPE), does not protect individually, but generally. Collective protection basically protects all people in areas at risk of falling, such as edges on roofs and buildings, bridges, stairs or even large machines, without the need for additional protective equipment. Technical implementation of measures for collective protection can be safety nets, scaffolding or so-called side protection. The best known and most common form - in everyday life as well as at work - is the (protective) railing .
Labor law basics
In the statutory and trade association requirements for fall protection at work, collective protection generally has priority over alternative protective measures. In DIN 4426: 2013, which is binding for occupational safety, with the title "Safety requirements for workplaces and traffic routes", it literally states: "When selecting the equipment, fencing has priority over anchorage devices for personal protective equipment against falls (PPE)." The BGI ( Employer's liability insurance association information) 5164 "Planning principles for anchor devices on roofs" gives collective unconditional priority over personal fall protection.
Locations
Typical locations for collective protection are stairs and bridges, but also skylights, photovoltaic modules, chimneys and roofs. In addition, collective protection is not installed permanently on construction sites, but only temporarily to protect the workers during the construction phase, for example in the form of scaffolding . Guard rails can be attached to the structure in various ways. In DIN EN 13374: 2013 “Temporary side protection systems”, a distinction is made between variants with “clamp”, “counterweight” or “fixed connection of the foot to the ceiling”. For buildings on which roof penetration is not desired, for example in production halls in the food or pharmaceutical industry, protective railings can be used that are welded to bitumen and foil surfaces. According to DIN EN 13374: 2013, a guardrail must have a minimum height of 100 cm; In accordance with DIN EN 14122-3 “Fixed access to machine systems”, which is applicable in industry, the minimum height of guardrails is even 110 cm. If a railing is attached to a roof edge that does not have a parapet , or if the parapet is lower than 10 cm, appropriate protection is necessary at this height, for example in the form of an additional skirting board.
Classification guardrail
In DIN EN 13374: 2013 three railing classes are defined for different angles of inclination, each of which is subject to different test criteria. A class A railing is recommended for roof surfaces with a slope of up to 10 °; This type of railing is subjected to a static load test according to the test procedure before it can be approved for the market. Class B guardrails are used for roof pitches of up to 30 ° - if the maximum fall height is less than 2 m, Class B side protection can also be installed with a roof pitch of up to 60 °. Class C guardrails are used at an angle of inclination between 30 ° and 45 °; if the maximum fall height is less than 5 m, these railings are also suitable for a roof pitch between 45 ° and 60 °. The tests necessary for certification are carried out dynamically for side protection devices of classes B and C in order to simulate a person falling or bumping into the railing.
