STEP 2: Importance of Proper Preventive Maintenance of Equipment and Machines (45minutes) Activity: Buzzing (5minutes) ASK students to pair up and buzz on the following questions for 5 minutes • What is preventive maintenance? ALLOW few pairs to respond and let other pairs add on points not mentioned WRITE their response on the flip chart/board CLARIFY and SUMMARIZE by using the content below • The goal of maintenance is to keep the production system in good working order at minimal cost • Maintenance –include all activities that maintain facilities and equipment in good working order so that a system can perform as intended • Goals of Maintenance-To keep production systems in good working order at minimal cost • Reasons for maintenance o To avoid production or service disruptions o To not add production or service costs o To maintain high quality o To avoid missed delivery dates • Preventive maintenance: goal is to reduce the incidence of breakdowns or failures in the plant or equipment to avoid the associated costs • Preventative Maintenance is a way to catch small issues with your machine before they become big issues OR involves maintenance performed to extend the life of the device and prevent failure • Preventive maintenance is “that function of manufacturing management that is concerned with day to day problem of keeping the physical plant in good operating condition” • Preventive maintenance is periodic o Result of planned inspections o According to calendar o After predetermined number of hours • Five Components of a maintenance 73 PST 05207 Quality Assurance of Pharmaceutical Products NTA Level 5 Semester 2 o Breakdown maintenance or corrective maintenance; Occurs when there is a work stoppage due to machine breakdown o Preventive maintenance; It is undertaken before the need arises and aims to minimize the possibility of un -anticipated production interruption or major breakdowns o Predictive maintenance; Conditions can be measured on a continuous basis and this enables the maintenance people to plan for an overhaul. o Routine maintenance; this includes activities such as periodic inspection, cleaning, lubrication and repair of production equipments after their service life o Planned maintenance; : it involves the inspection of all plant and equipments, machinery, buildings according to a predetermined schedule in order to service overhaul, lubricate or repair, before actual break down or deterioration in service occurs • Principle Objectives in Maintenance o To achieve product quality and customer satisfaction through adjusted and serviced equipment o Maximize useful life of equipment o Keep equipment safe and prevent safety hazards o Minimize frequency and severity of interruptions o Maximize production capacity – through high utilization of facility • Advantages o Reduces break down and thereby down time o Lass odd-time repair and reduces over time of crews o Greater safety of workers o Lower maintenance and repair costs o Less stand-by equipments and spare parts o Better product quality and fewer reworks and scraps o Increases plant life o Increases chances to get production incentive bonus • Importance of proper preventive maintenance of equipment and machines o Dependability of service o Assured quality o Prevent equipment failure o Cost control o Huge investment in equipment STEP 3: Considerations in Preventive Maintenance of Machines and Equipment (10 minutes) • Preventive Maintenance general considerations consists of o Proper design and installation of equipment o Documentation on Predictive Maintenance o Periodic inspection of plant and other equipments if properly functioning o Repetitive servicing and overhaul of malfunctioning equipment 74 PST 05207 Quality Assurance of Pharmaceutical Products NTA Level 5 Semester 2 o Adequate lubrication, cleaning and painting o Using of Personal Protective Equipments (PPE) o Preventive maintenance Benefits and Control STEP 4: Preventive Maintenance Procedures for Equipment and Machines (Reverse Osmosis Machine, Distiller, Autoclave, (50 minutes) Activity: Brainstorming (5 minutes) Ask students to brainstorm on the following question: • What are PM procedures for RO machine? ALLOW few students to respond WRITE their responses on the flip chart/ board CLARIFY and SUMMARISE by using the content below • Preventive maintenance procedures for reverse osmosis machine o Design, Construction and Preventive maintenance of USP Purified Water Systems o Reverse Osmosis (RO) is a well-established process o For an RO system to work reliably and economically, the unit and associated equipment must be routinely maintained o Reverse osmosis is the most economical method of removing up to 99% of feed water contaminants o Requires pretreatment to avoid damaging the membrane; o A Typical reverse osmosis preventive maintenance Checklist must be present in
