ABS material (acrylonitrile butadiene styrene) is a type of thermoplastic that is very resistant to impact or shock.

Its applications are several, for example is a material widely used in the manufacture of interiors or components of cars such as moldings, as well as in products for domestic use such as toys, tools, housings of electrical devices etc.

One of its most important characteristics is its great tenacidad in almost all types of temperatures.

Being a very hard material has good chemical resistance, low water absorption and high resistance to abrasion, where other types of plastics would be more brittle.

This type of material is becoming very famous in the particular field and widely used due to the great growth in the sales of domestic 3D printers, the main printing raw material.next to the PLA.

Identification of ABS
Parts that are made of ABS material must be marked in accordance with ISO 11469 (DIN 58840).

Clothing such as shirts, pants or reflective vests are an indispensable accessory that provides extra visibility to users and can help prevent possible accidents. For example, workers on public roads or state bodies.

These types of accessories are usually designed with bright colors, such as yellow or orange fluorescent, and incorporate reflective strip system that ayudan in low light situations to be seen by vehicles.

More information on this type of clothing and its regulations can be found in NTP 718 of the National Institute of Social Security and Hygiene at Work.

The signage in the companies besides recommendable is obligatory. Signaling emergency exit areas or fire extinguishers are crucial in case of fire or evacuation.
These signals can be divided into 5 groups:

1. 
   Warning signs:
   A warning sign is one that warns of a hazard or a hazard. Always with triangular shape, pictogram in black color and yellow background cOn black edges. By way of exception the bottom will be orange when dealing with harmful or irritating materials.
2. 
   Prohibition signs:
   A prohibition sign is one that prohibits behavior that is likely to cause a hazard. Always in a round shape, black pictogram with white background, cross strip and red border.
3. 
   Signs of obligation:
   A sign of obligation is that whichThe user to perform an action or procedure, its function is to prevent unnecessary accidents in the work area. Always circular, with white pictogram on a blue background.
4. 
   Signs of fire fighting equipment:
   They indicate the exact position of the materials or extinguishing systems, whether fire hydrants, fire extinguishers or fire-fighting buttons. Always rectangular or square,White pictogram on red background.
5. 
   Signs of rescue and rescue:
   These signals guide the user in the course of an evacuation or emergency situation. They are used to control the flow of people at their exit and prevent accidents. There are also these types of signs indicating the position of first aid kits or services or rescue devices.

A convex mirror is a piece of a sphere with reflective part on the outside (outer deformation out). They are also known as diverging mirrors, that is, light rays coming from a point, to be reflected, and not away intersect each other. For this reason the convex mirrors are not actual images. Convex mirrors for signaling can be installed both outdoors and indoors, Dependon the material. These mirrors are designed to see and be seen, particularly suitable for areas with low visibility to prevent accidents of pedestrian traffic, vehicle traffic and surveillance. can also be used for:
- Parking lots or parking
- Streets dangerous crossings
- Department Stores
- Shops and businesses
- Supermarkets
- Hospitals
- Factories and industries
- Piers
- Office buildings
- Schools
- Museums

Before deciding to mirror needs, you should always take into account the following parameters:

1. Distance between the observer and the mirror. That is, the distance at which the observer will be the mirror when viewing.
2. Number of addresses to be controlled.

We attach some approaches depending on the diameter of the convex mirror.

• diameter mirror 450mm -> 6 meters away from the mirror.
• 600mm diameter mirror -> 8 meters away from the mirror.
• 800mm diameter mirror -> 10 meters away from the mirror.
• 1000mm diameter mirror -> 14 meters away from the mirror.
