Compiled by: Joan Cherono

Drafting garment pattern pieces is a fundamental skill for fashion designers, enabling the translation of creative ideas into physical forms. In Kenya’s dynamic fashion industry, mastery of pattern construction supports the production of well-fitting garments that meet the preferences of diverse clientele. Draft patterns serve as templates from which fabric is cut, making accuracy and detail paramount to avoid costly errors in production. This chapter focuses on the essential Personal Protective Equipment (PPEs) used during pattern drafting to ensure safety, efficiency, and quality in the workspace.

3.1 PPEs

Personal Protective Equipment (PPE) is critical in fashion design workshops and studios, especially during pattern drafting activities that involve sharp tools, chemicals, and repetitive motions. In Kenyan fashion design environments, from small tailoring shops in Nairobi to larger apparel manufacturing firms, using appropriate PPE safeguards the health of designers and technicians. Proper PPE prevents injuries, reduces exposure to hazardous substances, and fosters a professional work culture that aligns with Occupational Safety and Health Act (OSHA) regulations.

3.1.1 Types of PPE Used in Garment Pattern Drafting

Understanding the range of PPE available for pattern drafting is essential for maintaining safety without compromising precision. The nature of pattern construction, cutting, marking, pinning, and handling materials, exposes users to various risks that PPE can mitigate.

Protective Gloves

Protective gloves shield hands from cuts caused by scissors, rotary cutters, and pins. They also prevent skin irritation from adhesives or fabric treatments used during pattern making. In some Kenyan fashion workshops, gloves made of lightweight nitrile are preferred for their dexterity, allowing fine manipulation of tools without sacrificing protection.

Eye Protection

Eye safety glasses or goggles protect against accidental splashes of marking fluids or contact with sharp tools. For example, designers using tailor’s chalk or spray adhesives benefit from goggles to avoid irritation. Eye protection is especially important in larger apparel factories where multiple processes occur simultaneously.

Aprons and Protective Clothing

Aprons or smocks protect personal clothing from stains caused by fabric markers, chalk, and adhesives. They also provide a barrier against minor cuts or scratches. In Kenyan institutions such as garment training colleges, wearing aprons is standard practice to maintain hygiene and prevent cross-contamination between fabrics.

Foot Protection

Closed-toe shoes are recommended to protect feet from falling sharp tools such as scissors or weights. In busy fashion studios, accidental drops are common, and proper footwear reduces the risk of injury. Non-slip soles further enhance safety on smooth workshop floors.

Respiratory Protection

Though less common in basic pattern drafting, respiratory masks may be necessary when using spray adhesives or solvents in poorly ventilated areas. Kenyan designers working in confined spaces or with chemical treatments should consider masks to reduce inhalation of harmful fumes.

3.1.2 Importance of PPE in Pattern Drafting Safety and Quality

The use of PPE is not only a regulatory requirement but also a key factor in ensuring the quality and efficiency of pattern construction. Kenyan fashion designers who adopt PPE experience fewer workplace injuries, enabling uninterrupted work schedules and consistent output.

Injury Prevention

Sharp tools like rotary cutters and scissors are integral to pattern drafting but pose a risk of cuts and punctures. Gloves and protective clothing reduce the incidence of such injuries, which can otherwise lead to downtime and medical expenses.

Prevention of Contamination

Fabric markers and adhesives can stain patterns or damage delicate fabrics. Wearing aprons and gloves minimizes accidental contamination, preserving the integrity of both patterns and fabric samples, which is crucial for sample-making in fashion houses.

Enhanced Focus and Productivity

When designers feel safe and comfortable, they can focus better on precision tasks such as marking seam allowances and adjusting pattern shapes. PPE reduces distractions caused by minor injuries or discomfort, contributing to higher productivity in garment production units.

Compliance with Safety Standards

Adhering to PPE protocols aligns Kenyan fashion enterprises with national workplace safety laws, such as those enforced by the Directorate of Occupational Safety and Health Services (DOSHS). Compliance improves the reputation of businesses and ensures eligibility for government contracts or partnerships.

Promotion of Professionalism

Consistent use of PPE signals professionalism and commitment to best practices. In fashion shows or client presentations, well-organized workshops with visible safety measures inspire confidence in clients and stakeholders.

3.1.3 Selection Criteria for PPE in Fashion Pattern Drafting

Choosing appropriate PPE requires consideration of specific hazards, comfort, and the nature of tasks involved in pattern construction. Kenyan fashion studios vary widely in scale and resources, influencing PPE selection.

Hazard Assessment

Identify the main risks present, such as cuts, chemical exposure, or repetitive strain, to select PPE that directly addresses these dangers. For example, a workshop using spray adhesives must prioritize respiratory masks, whereas a small tailoring studio may focus on gloves and aprons.

Comfort and Dexterity

PPE should allow freedom of movement and tactile sensitivity, especially gloves that enable fine motor skills necessary for accurate cutting and marking. Lightweight materials and ergonomic designs are preferred to prevent fatigue during long drafting sessions.

Durability and Maintenance

Choose PPE that withstands frequent use and can be easily cleaned or replaced. Kenyan designers often work extended hours; thus, durable aprons and gloves that maintain protection over time are cost-effective investments.

Availability and Cost

Consider locally available PPE options that meet safety standards without excessive cost. In Kenya, sourcing from reputable suppliers ensures authenticity and compliance with safety regulations, balancing affordability with protection.

Compatibility with Other Equipment

Ensure PPE does not interfere with other tools or attire worn during pattern drafting. For instance, bulky gloves might hinder handling of small pins, so selecting slim-fitting gloves is advisable for detailed work.

3.1.4 Maintenance and Proper Use of PPE in Pattern Drafting Workshops

Effective use of PPE depends on correct wearing, regular maintenance, and proper storage to preserve functionality and hygiene. Kenyan fashion designers must integrate these practices into daily routines to maximize safety benefits.

Cleaning Protocols

Gloves, aprons, and eye protection should be cleaned according to manufacturer instructions to remove stains, adhesives, and contaminants. For example, aprons made of washable fabrics can be laundered regularly, while goggles require gentle wiping with appropriate solutions.

Inspection Before Use

Regularly inspect PPE for signs of wear, damage, or contamination. Torn gloves, scratched goggles, or stained aprons reduce protection and should be replaced promptly to avoid accidents.

Correct Wearing Techniques

Ensure PPE fits correctly and is worn consistently during all pattern drafting activities. Ill-fitting gloves can impair dexterity, while improperly worn masks fail to provide adequate respiratory protection.

Safe Storage

Store PPE in clean, dry areas away from direct sunlight or chemicals to prevent degradation. In Kenyan design studios, designated PPE stations help maintain order and quick access.

Training and Awareness

Conduct periodic training sessions on the importance and correct use of PPE. This fosters a safety culture among designers and trainees, reducing negligence and promoting compliance with safety policies.
