Complete Summary and Solutions for Safety and Security – Health and Physical Education Textbook for Class XI, Chapter 7

Full Chapter Summary & Detailed Notes - Safety and Security Class 11 NCERT

Overview & Key Concepts

Chapter Goal: Emphasize safety in sports facilities and prevention of injuries; address substance abuse hazards. Exam Focus: Safety measures (grounds/gym/pool), injury causes/prevention, tobacco/alcohol effects. 2025 Updates: Integration with wellness programs, anti-abuse campaigns. Fun Fact: Proper fitness prevents up to 60% injuries via better reactions.
Wider Scope: From facility design to adolescence health risks; sources: Activities (school safety audit), think/reflect (substance myths). Core Idea: Prevention better than cure; secure environment builds confidence.
Expanded Content: Include modern hazards (e.g., synthetic surfaces); point-wise for recall; 2025 relevance like digital safety apps.

Introduction to Safety in Sports

Importance: Games develop holistic health but require security to avoid phobias/injuries; coaches/players prioritize winning but must follow rules.
Modern Relevance: Competition intensity demands systematic training with safety; apply to technical sports like gymnastics/swimming.
Example: Remove hazards like stones/wires; separate warming-up areas.
Expanded: Do You Know? No tree cutting due to land scarcity; Kabaddi/Kho-Kho on safe synthetics.

Conceptual Diagram: Safety Layers (Inferred from Text)

Facilities (ground/equip/uniform) → Gym/Pool Measures → Injury Prevention → Substance Awareness; visualizes layered protection.

Why This Guide Stands Out

Comprehensive: All measures point-wise, abuse effects analyzed; 2025 with anti-tobacco drives, holistic risk reduction.

Safety in Facilities: Grounds, Instruments, Uniforms

Sports Ground: Remove hazards (wires/bushes/stones); hard surfaces for basketball/tennis; fencing 6m away; separate seating.
Instruments: High-standard materials; no damaged equip; separate surfaces per sport.
Uniforms: Proper shoes (arch support/balance); light T-shirts (non-sweat absorbing); avoid allergies.
Think & Reflect: Activity 7.1 - School safety audit.
Expanded: Construction prioritizes safety over competition.

Gymnasium & Swimming Pool Safety

Gym: Safe equip storage, warm-up areas, non-slippery floors, proper lighting/sanitation; no heavy lifts alone.
Pool: Separate beginner/advanced; lifeguards with devices (ropes/jackets); chlorination/cleaning; no deep-end without supervision; proper uniforms/showers.
Activity: 7.2 - Gather pool/gym injury info.
Expanded: Human power/water quality essential.

Exam Activities

Discuss facility steps (Act 7.3); analyze substance case like Mukesh (gutkha death).

Injury Prevention & Causes

Why Injuries Occur: Poor equip/rules knowledge, lack fitness, unsafe lifts.
How to Prevent: Warm-up, safety gears, rule adherence, fitness conditioning, coach supervision, nutrition/shoes.
Expanded: Technical practice; differently-abled needs.

Substance Abuse in Adolescence

Hazards: Tobacco (nicotine/addiction/cancers), smokeless (oral cancer); alcohol similar risks; affects growth/personality.
Effects: Lung/oral cancers, addiction, mood volatility, pregnancy harm; women targeted.
Prevention: Say NO; role models; treatment/support.
Do You Know: Half youth tobacco users die mid-age; nicotine as pesticide.
