Question

al subir o bajar una pendiente con una carga, la carga debe ser:
cuesta arriba
cuesta abajo
no importa
todas las anteriores

antes de colocar la carga en las horquillas, el operador de pit debe:
inspeccionar la carga para verificar la estabilidad.
nada, solo cárgalo
cargarla pero sacudirla con el pit para que no se caiga nada
todas las anteriores

al cargar sistemas de estanterías, los operadores de pit deben:
colocar objetos pesados en el fondo.
colocar artículos ligeros en la parte superior.

Explanation:

First Question:

When moving a load up or down a slope, for safety (to prevent the load from sliding down unexpectedly), the load should be oriented uphill (cuesta arriba) to maintain control and stability. The other options (cuesta abajo would let it slide, no importa is incorrect, todas las anteriores is wrong as only cuesta arriba is correct) are not valid.

Before placing a load on forks (of a PIT - Powered Industrial Truck), safety protocols require inspecting the load for stability to avoid accidents (like load shifting or falling). The other options (nada, solo cárgalo is unsafe; sacudirla with PIT is dangerous; todas las anteriores is wrong) are incorrect.

For loading shelving systems with a PIT, best practice is to place heavy objects at the bottom (for stability, lower center of gravity) and light ones on top. So both "Colocar objetos pesados en el fondo" and "Colocar artículos ligeros en la parte superior" are correct, but if we consider the options (assuming it's a multiple - correct or choosing the relevant ones), these are the safe practices. If we take the first option shown:

Answer:

A. Cuesta arriba
