EXPLOSIVES QUIZ ANSWERS

⸻ Overview of the NYPD Organization: The New York City Police Department (NYPD) is one of the largest and most complex police departments in the world. It has many different parts that work together to keep the city safe. Each part is responsible for specific tasks—like patrol, investigations, traffic, and emergencies. ⸻ What is the Special Operations Bureau? The Special Operations Bureau (SOB) is a special branch inside the NYPD that handles dangerous or unusual situations that regular police officers are not trained for. They step in when there are big emergencies, high-risk situations, or special security needs. It is part of the Chief of Special Operations, who supervises all the units under this bureau. ⸻ What Units Are in the Special Operations Bureau? There are several special units inside the Special Operations Bureau: ⸻ 1. Emergency Service Unit (ESU) • This is like the NYPD’s version of SWAT. • Officers in ESU are trained for: • Rescue operations (like saving people trapped in cars or buildings) • Dealing with armed suspects or barricaded people • Handling hazardous materials (hazmat) • Counter-terrorism • They carry heavy equipment, wear special gear, and often work with other first responders (like FDNY or EMS). ⸻ 2. Aviation Unit • This team uses helicopters to: • Help during search and rescue missions • Watch over crowds or traffic from the air • Support police on the ground during emergencies ⸻ 3. Harbor Unit • These officers patrol the waterways around NYC (like rivers, harbors, and ports). • They stop illegal activities like smuggling or unsafe boating. • Also used in rescue operations during water emergencies. ⸻ 4. Canine Unit (K9) • Police dogs trained to: • Find drugs or explosives • Track missing people • Help during searches • Handlers work closely with the dogs to respond quickly to dangerous situations. ⸻ 5. Mounted Unit • Officers on horses who work mostly in: • Parks, parades, protests, and large events • The horses help the officers move through crowds more easily and stand out. ⸻ 6. Disorder Control Unit • Handles large protests, riots, or big public gatherings • Trains officers to deal with crowd control, especially when things might get out of hand ⸻ Why the Special Operations Bureau Is Important: • These units are highly trained and always ready to respond when something dangerous or unusual happens. • They support regular NYPD officers by doing specialized work. • They play a big role in keeping people safe during big events, disasters, or threats. ⸻ Leadership: • The Chief of Special Operations is the person in charge of the entire bureau. • This chief makes sure all the teams are trained, equipped, and ready to help when needed. ⸻ In Short: The Special Operations Bureau is like the NYPD’s elite emergency team. They do things regular officers cannot do, like using helicopters, police dogs, rescue tools, or dealing with explosives. Whether it’s on land, water, or air—they’re prepared for all types of dangerous situationsg

ACIDS a) Sulphuric Acid: H250, Commercial names: oll of vitriol, "battery acid" Propert/es: • good dehydrating agent (I.e. removes water from substances) • strongly exothermic reaction when mixed with water • concentrated form chars some types of organic material (e.g. sugars) as a result of dehydrating action • reacts with some metals, but often slowly • good electrolyte (conducts electricity) • concentrated sulphuric acid is 98% HSO, and 2% water (18 M HSO4) Common uses: • production of sulphates • manufacturing fertilizers, explosives, dyes, insecticides, detergents, plastics • used to absorb waler and keep chemicals/nonaqueous solutions free of water • used in car batterles as an electrolyte b) Hydrochloric Acid: HCI Commercial name: • muriatic acid Properties: • good electrolyte • concentrated solutions have a choking odour • reacts with some metals, but often slowly • concentrated hydrochloric acld is 37% HCl In water (12 M HCI) Common uses: • production of chlorides • cleaning metal products (removes metal oxides) and bricks • catalyst in some chemical reactions • "stomach acid" is a dilute solution of HCi; stomach acid activates a protein-digesting biological calalyst called an "enzyme" • removing "boller scale", which consists of calcium and magnesium carbonate •) Nitric Acid: HNO Commercial name: (none, other than "nitric acld") Properties: • colours protein yellow (this is a nonspecille test for the presence of protein). Hence, turns skin yellow on contact. • very reactive, quickly attacks almost all metals • concentrated nitric acid is 69% HNOg In water (16 M HNOg) Common uses: • production of nitrates • manufacturing fertilizers, explosives, dyes d) Acotic Acid: CHCOOH Commercial name: 5% aqueous solution is called "vinegar" Properties: • non-electrolyte when concentrated (99 - 100%, 17 M); weak electrolyte when diluted • only affects highly reactive metals Common uses: • making acetates • food preservation ("pickles") • manufacturing textlies and plastics
