1. Safety tips

How do international standards define laser products?

The International Electro technical Commission (IEC) classifies laser products into four main categories according to their potential level of danger:

• Class 1: No danger. Under normal use conditions, the output power of the laser is extremely low and does not cause damage to the eyes or skin.
• Class 2: Low risk. Laser light has a low output power and is usually visible light, which can cause limited damage to the eyes, but it is recommended to avoid looking directly at them for long periods of time.
• Class 3: Moderate risk. It is classified into Class 3R and Class 3B, which may cause damage to the eyes and skin and requires proper protective measures.
• Class 4: High risk. The output power of the laser is very high, which can cause serious injury to the eyes, skin and surrounding materials, and strict protective measures must be taken.

It is noted that some other optical devices such as cameras, camcorders, video projectors, etc. may be damaged if exposed to excessive laser radiation.

2. Precautions for operation

The laser system is a precision device containing a number of sensitive optoelectronic components. Do not drop it or subject it to physical impact.

The laser system is not waterproof or dust-proof.

If using in rain, snow or similar harsh environmental conditions, be sure to use a suitable cover or housing.

Do not place the laser system in an overheated area, such as a car in direct sunlight. High temperatures can cause serious damage to the system.

The laser system contains precision electronic circuits. Do not attempt to disassemble the laser by yourself. If the laser is suddenly brought from a cold room to a warm room, condensation may form on the laser and internal parts.

Do not open the device immediately if it is exposed to drastic temperature fluctuations, such as after transportation. The resulting condensed water may damage your equipment. Turn the device off until room temperature is reached.

Turn off the laser luminaire and allow the laser luminaire to cool for a period of time before turning it off.

Do not run the equipment without a laser light fixture!

Do not shake the equipment. Avoid brute force when installing or operating equipment.

Never lift the laser light fixture on the projector head, as it may damage the mechanism. Always fix the laser fixture on the transport handle.

When choosing a location for installation, make sure the equipment is not exposed to extreme heat, moisture, or dust. The minimum distance between the light output and the illuminated surface must be greater than 8 m.

When assembling, removing or servicing laser lamps, ensure that the area below the installation position is blocked.

Always secure the laser fixture with a suitable safety rope. Secure the safety rope only at the correct hole.

The laser fixture should only be operated after checking that the housing is firmly closed and all screws are tightened.

If the objective lens or any housing cover is open, the laser luminaire must not be lit, as discharging the laser luminaire may cause burns. They explode and emit high ultraviolet radiation, which can cause burns.

The maximum ambient temperature of 45°C shall not be exceeded.

3. Safety matters

The laser system is a precision device containing a number of sensitive optoelectronic components. Do not drop it or subject it to physical impact.

1. If the laser display or show is under the continuous control of an operator who can immediately terminate laser beams in the event of a problem, a minimum separation distance of 3 m in height and 2.5 m laterally should be maintained between beams that exceed the spectator MPE and any surface upon which spectators can reasonably be expected to stand. This condition is shown in Figure 1 and Figure 2.

Figure 1: Audience/spectator separation auditorium scenario with operator in control, showing distances and zones.

Figure 2: Audience/spectator separation nightclub scenario with operator in control, showing plan view and side elevation with distances and zones.

4. If a projection area terminates onto a balcony or near a window, where spectators can view the laser effect, and the exposure level at the termination point is likely to be in excess of the spectator MPE, the beams should terminate no higher than the floor level of the balcony if it has an opaque solid barrier. This condition is shown in Figure 3.

Figure 3: Audience/spectator separation near a balcony with operator in control, showing termination point of laser effect.

5. If the laser display or show is not under the continuous control of an operator who can immediately terminate laser beams in the event of a problem, a minimum separation distance of 3m in height and 2.5m laterally should be maintained between beams that exceed the spectator MPE exceeded by more than a factor of 5 in the space between 3m and 6m above any surface upon which spectators can reasonably be expected to stand. This condition is shown in Figure 4.
