Introduction

In recent years, the vigorous development of China's performance industry, the rapid development of performing arts equipment and stage technology, and the scope of application has become increasingly widespread. At the same time, pass Due to technological advancement and application complexity, the stage curtain has brought many new safety hazards and significantly increased the accident rate. Such as. stage There are more and more theaters with unsatisfactory flame retardant treatment or long-term failure, and there are many accidents when the safety distance between the pole and the pole is not guaranteed.

Health, lighting caused the smoldering of the curtain, and even more accidents caused by fire. The curtain has become one of the important hidden dangers of the safety of the show, especially the first source of risk for a theater fire accident. The safety of the curtain is directly related to the safety of the audience and the cast members, and is related to the expensive design.

Prepared property security. Therefore, the development of curtain safety standards has become one of the important guarantees for standardizing the safety of performances.

In terms of the factors that cause the security of the curtain, this section is divided into different performance standardization objects, which are divided into performance safety technical standards and performance safety.

Management standards, performance safety work standards. Among them, the technical standards are for the curtain products, and the management standards are for the organization.

Standards are required for operators.

This section is based on the scientific analysis of major safety accidents and common safety incidents that have occurred on the stage curtains.

The technical requirements, management specifications and operating procedures in the use of the curtain are standardized to reduce and eliminate potential safety hazards and avoid common safety accidents.

Or a major accident occurred. At the same time, the provisions of this section and some provisions of the provisions are intended to cause safety warnings to further improve safety in the industry.

awareness.

The standard drafting group consulted extensively on industry suggestions and opinions, and inquired about a large number of relevant materials at home and abroad, and carefully summarized practical experience and extensive this section has been prepared on the basis of comments.

This part is essential for the design, installation and dismantling of the stage curtain, but the safety requirements of this part cannot be substituted for safety.

Other safety work such as education, preventive measures and safety supervision.

If any parts of this part need to be revised and supplemented during the implementation process, please send your comments and relevant materials to the China Academy of Arts and Technology.
