Multiple Trigger Colliders on One GameObject

I have two colliders on my elevator, one BoxCollider at the door and a CapsuleCollider on the inside of the elevator.

How do I check which Collider was triggered so I can execute different blocks of code?

This is my GameObject:

This is my code:

 using UnityEngine;
 using System;
 using System.Collections;
 
 public class Elevator : MonoBehaviour {
 
     public Transform elevator;
     public bool open = false;
     public bool verbose = false;
 
     private bool moving = false;
     private bool inElevator = false;
 
     public void Start() {
         
     }
 
     public void Update() {
         
     }
 
     public void OnTriggerEnter(Collider elevatorCollider) {
         if(elevatorCollider.GetType().ToString().Equals("BoxCollider")) {
             openDoors();
         }
     }
 
     public void OnTriggerExit(Collider elevatorCollider) {
         if(elevatorCollider.GetType().ToString().Equals("BoxCollider")) {
             closeDoors();
         }
     }
 
     public void OnTriggerStay(Collider elevatorCollider) {
         if(elevatorCollider.GetType().ToString().Equals("CapsuleCollider")) {
             Debug.Log("CC");
         }
     }
 
     private void openDoors() {
         if(!open && !moving) {
             elevator.animation["Default Take"].speed = 1;
             elevator.animation.Play("Default Take");
             open = true;
             if(verbose) Debug.Log("Elevator Opening");
         }
     }
 
     private void closeDoors() {
         if(open && !elevator.animation.IsPlaying("Default Take") && !moving) {
             elevator.animation["Default Take"].speed = -1;
             elevator.animation["Default Take"].time = elevator.animation["Default Take"].length;
             elevator.animation.Play("Default Take");
             open = false;
             if(verbose) Debug.Log("Elevator Closing");
         }
     }
 
 }
