Abstract

Footwear are one of the consumer materials and an engineering product, Globally China is the largest footwear production country, and India is the second largest footwear production after China for approximately 9% of the global annual production of 22 million pairs. The footwear production industry having many more working process and machinery utilization that sector is fragmented and close to 75% footwear production in unorganized sector including small scale and medium enterprises. To make the footwear comfortable, durable, to be to protect from injuries or to make it look very attractive different materials are to be used. i.e., leather, fabric, plastic, Rubber, Foam materials, metallic, chemicals, wood. During this production activity at different sections, various Hazards exists which may harm to employee and surrounding if adequate measure not ensured. In this review article in footwear industry with control measure are monitored and required to avoid any untoward incident, thoroughly discussed.

Keywords: Leather; Rubber sole; chemical; Hazards safety; Fire; Electrical; Machineries; Training; SOP

Introduction

Footwear industries plays a major role in the country economy The knowledge and practice of footwear manufacturing involves general processing of closing the upper like skiving edge treatment reinforcement of upper and lining components perforation Gimping sewing and full shoe production activity. Footwear production mostly unorganized small scale and medium scale industry and multinational branded MNC footwear industry also involved for this bulk production process. It require many of the manpower and materials chemical other synthetic materials many other machineries also involved for making one pair of shoe due to this production base it will meet many more technical issues employee hazardous incident production problems and quality issues factors also so this article mainly focused the employer and surrounding Hazardous problems and it will recommended the accident prevention techniques to avoid such type of up normal problems in footwear industry [1]. Robust manufacturing set up and good manufacturing practices is the strength for the quality product and high productivity. It takes time in month years to ensure good manufac turing practices to build the up a safe working environment and maintain organization reputation. But un incident may destroy all efforts, reputation of the organization including damage of life. Properly and environment at large. Footwear manufacturing process is not easy activity due to different machinery activities and it involves different hazards. Appropriate safety measure may lead to a serious incident may be cause harm to human being as well as to environment due to use of different hazardous chemical. It is moral responsibility of an employer to ensure identification of different hazards and take adequate steps to minimize the risk due to identified in this special review article. It will help to improve the safety prevention control measure in at all levels of workplace and ensure Zero incident in all process activity areas. Hence a review of Hazards and Prevention safety measures required in Footwear industry is essential to control unwanted Hazards.
